Extensions.cs contains extension methods that enhance existing C# classes thus making life easier for developers.

The following classes have been extended:

- System.Array
- System.Collections.Generic.Dictionary
- System.Collections.Generic.List
- System.DateTime
- System.Diagnostics.Process
- System.Double
- System.Int16
- System.Int32
- System.Int64
- System.Logging (added)
- System.Long
- System.Net.WebException
- System.Object
- System.String
- System.Text.StringBuilder
- System.Timer
- System.TimeZoneInfo
- System.UInt16
- System.UInt32
- System.UInt64
- System.ULong

with these methods:

• BeginsWith()

  Reduces checking if a given string starts with another given string
  from this:
  (str.ToLower().Substring(0, target.Length) == target.ToLower())
  to this:
  str.BeginsWith(target, true)
  
  

• Bigest()

  Return the bigest of two given values.
  For example:
  Bigest(23, 31)
  will return
  31

• CompoundInterest()

  _Calculate compounded interest end value given an amount, percent
  interest per year and number of years.
  For example:
  double val = 100.00;
val.CompoundInterest(5,
10,
Constants.CompoundFrequency.Yearly);
  will return 162.889462677744 _

• ContainsAny()

  Checks if the given string contains any of a list of characters or
  strings provided.
  For example:
  "abcdef1234567890".ContainsAny(Constants.HexChars)
  will return True.
  
  

• ContainsOnly()

  Checks if the given string contains only characters or strings
  in the list provided.
  For example:
  "abcdef1234567890".ContainsOnly(Constants.HexChars)
  will return True while
  "abcdefg1234567890".ContainsOnly(Constants.HexChars)
  will return False because of the "g".

• CopyTo()

  Copies a given length of bytes from a byte[] starting at a definable
  offset.
  For example:
  byte[] b1 = System.Text.Encoding.UTF8.GetBytes("blog.cjvandyk.com rocks!");
byte[] b2 = b1.CopyTo(10);
byte[] b3 = b1.CopyTo(10, 5);
  will result in the following arrays:
  98 108 111 103 46 99 106 118 97 110 100 121 107 46 99 111 109 32 114 111 99 107 115 33
98 108 111 103 46 99 106 118 97 110
99 106 118 97 110 100 121 107 46 99

• DoubleQuote()

  Return the given string encased in double quotes.
  For example:
  printf("https://blog.cjvandyk.com/sites/Rocks");
printf("https://blog.cjvandyk.com/sites/Rocks".DoubleQuote());
  will return
  https://blog.cjvandyk.com/sites/Rocks
"https://blog.cjvandyk.com/sites/Rocks"

• Elevate()

  Restarts the current process with elevated permissions.
  For example:
  System.Diagnostics.Process.GetCurrentProcess().Elevate(args)
  will restart the current console app in admin mode.

• Err()

  Write an Error message to active channels (console, event log, file)
  using the System.Logging class.

• ExceedsLength()

  Checks if a referenced offset exceeds the length of the string.
  Optionally increments the offset as well.
  For example:
  "https://blog.cjvandyk.com Rocks!".ExceedsLength(30)
  will return False while
  "https://blog.cjvandyk.com Rocks!".ExceedsLength(31, false)
  will also return False and
  "https://blog.cjvandyk.com Rocks!".ExceedsLength(31)
  will return True.

• Get()

  Language extension for properties. Use to set the value of the
  extension property in question.
  For example:
  Microsoft.SharePoint.Client client = new Microsoft.SharePoint.Client("https://blog.cjvandyk.com");
client.ExecutingWebRequest += ClientContext_ExecutingWebRequest;
client.Set("HeaderDecoration", "NONISV|Crayveon|MyApp/1.0");
  This allows the creation of the extension property "HeaderDecoration"
  which can be changed as needed. Later in the delegate method we
  refer back to the extension property value thus:
  private void ClientContext_ExecutingWebRequest(object sender, WebRequestEventArgs e)
{
e.WebRequestExecutor.WebRequest.UserAgent = (string)e.Get("HeaderDecoration");
}
  NOTE: We did not have to access the ClientContext class in order to
  retrieve the "HeaderDecoration" value since the extension was
  done against the System.Object class. As such, any object can
  be used to retrieve the extension property value, as long as
  you know the key value under which the property was stored and
  you know the type to which the returned value needs to be cast.
  A derived override method for Get() and Set() can be defined
  using specific class objects if finer controls is needed.
  

• GetExecutingAssembly()

  Gets the current Entry or Executing assembly through reflection.

• GetExecutingAssemblyName()

  Gets the name of the current assembly, optionally escaped.

• GetNthPrime()

  Get the Nth prime number. It will serialize the list of discovered
  prime numbers to file in order to eliminate duplicate calculation
  of prime numbers. Use Universal.PrimeStatePath to override the
  path where the discovered list of prime numbers is saved.
  For example:
  Extensions.Universal.GetNthPrime(1000)
  will return the 1000th prime number - 7919.

• GetNthPrimeAsync()

  Get the Nth prime number using multi threading and asynchronous
  processing. It will serialize the list of discovered
  prime numbers to file in order to eliminate duplicate calculation
  of prime numbers. Use Universal.PrimeStatePath to override the
  path where the discovered list of prime numbers is saved.
  For example:
  Extensions.Universal.GetNthPrime(1000)
  will return the 1000th prime number - 7919.

• GetSiteUrl()

  Given a full SharePoint Online object URL, this method will return
  the site collection part of the URL.

  would return https://crayveon.sharepoint.com/sites/TheSite

• GetTenantUrl()

  Given a full SharePoint Online object URL, this method will return
  only the tenant part of the URL.
  For example:
  "https://crayveon.sharepoint.com/sites/TheSite/lists/TheList".GetTenantUrl()
  would return https://crayveon.sharepoint.com

• GetTimeZoneString()

  Get the registry ID string that can be used with
  TimeZoneInfo.FindSystemTimeZoneById() for time zone convertions.
  For example:
  System.TimeZoneInfo.FindSystemTimeZoneById(
Extensions.TimeZoneInfo.GetTimeZoneString(
Constants.TimeZone myZone))
  will return the proper string to use in the call.

• GetUrlRoot()

  Get the URL root for the given string object containing a URL.
  For example:

  will return True whereas
  "abc123".IsChar(new char[] {'a', 'c'})
  will return False.

• IsDateTime()

  Validates that the given string is a valid date/time given the format.
  It provides an easy way to validate date string input.
  For example these:
  "20170704033333".IsDateTime("yyyMMddHHmmss")
"07/27/2017 03:33:33".IsDateTime("MM/dd/yyyy HH:mm:ss")
"27/07/2017 03:33:33".IsDateTime("dd/MM/yyyy HH:mm:ss")

  will all return True whereas these:
  "2017070403333".IsDateTime("yyyMMddHHmmss")
  2017/07/04 03:33:3 is clearly missing another digit.
  "07/27/2017".IsDateTime("dd/MM/yyyy HH:mm:ss")
  07/27 fails because there isn't 27 months.
  "27/07/2017".IsDateTime("MM/dd/yyyy")
  27/07 fails for the same reason.
  will return False.

• IsEmail()

  Validates that the given string object contains a valid email address.

  "https://blog.cjvandyk.com/sites/Approval".IsUrlRootOnly()
  will return False.

• IsVowel()

  Checks if the given char/string is an English vowel.
  This allows the developer the ability to check a string without
  having to first convert to a char e.g. as a substring return.
  For example:
  "test".Substring(2, 1).IsVowel()
  will return False since the "s" is checked whereas
  "test".Substring(1, 1).IsVowel()
  will return True since the "e" is checked.

• IsZipCode()

  This method returns the number of lines/sentences in the given string
  object.

• Load()

  Language extension providing a universal method to all objects
  that allows them to be deserialized from disk.
  Does NOT require the [Serializable] property on object.
  For example:
  ComplexClass myClass = new ComplexClass();
myClass = myClass.Load("My file path");
  Use .Save() to save objects to disk.

• LoremIpsum()

  Poplates the given string with a given number of paragraphs of dummy
  text in the lorem ipsum style. For example:
  "".LoremIpsum(2)
  would yield
  "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer
  aliquam arcu rhoncus erat consectetur, quis rutrum augue tincidunt.
  Suspendisse elit ipsum, lobortis lobortis tellus eu, vulputate
  fringilla lorem. Cras molestie nibh sed turpis dapibus sollicitudin
  ut a nulla. Suspendisse blandit suscipit egestas. Nunc et ante mattis
  nulla vehicula rhoncus. Vivamus commodo nunc id ultricies accumsan.
  Mauris vitae ante ut justo venenatis tempus.
  
  Nunc posuere, nisi eu convallis convallis, quam urna sagittis ipsum,
  et tempor ante libero ac ex. Aenean lacus mi, blandit non eros luctus,
  ultrices consectetur nunc. Vivamus suscipit justo odio, a porta massa
  posuere ac. Aenean varius leo non ipsum porttitor eleifend. Phasellus
  accumsan ultrices massa et finibus. Nunc vestibulum augue ut bibendum
  facilisis. Donec est massa, lobortis quis molestie at, placerat a
  neque. Donec quis bibendum leo. Pellentesque ultricies ac odio id
  pharetra. Nulla enim massa, lacinia nec nunc nec, egestas pulvinar
  odio. Sed pulvinar molestie justo, eu hendrerit nunc blandit eu.
  Suspendisse et sapien quis ipsum scelerisque rutrum."
  

• Match()

  Checks if the current string matches a given search mask.
  It ignores duplicate '' in the mask. '' is matched against
  0 or more characters. Duplicate '?' is treated as requiring
  the number of characters. '?' is matched against 1 or more
  characters.
  For example:
  "abcdefgh".Match("***a?c*")
  will return True while
  "abcdefgh".Match("***ac*")
  will return False but
  "abcdefgh".Match("?a?c*")
  will also return False because the first '?' requires a character
  before 'a'.

• MorseCodeBeep()

  Takes a given System.String representing Morse code and audiblize
  it according to standards.
  https://www.infoplease.com/encyclopedia/science/engineering/electrical/morse-code
  Assumes the input value to be in Morse code format already.
  Use .ToMorseCode() to pre-convert text if needed.

• NewCustomGuid()

  Returns a custom GUID starting with a custom string.
  For example:
  Extensions.NewCustomGuid("012")
  will return a new GUID that starts with "012".

• Print()

  Print the byte[] to console, separated by spaces and space padded
  on the right to allow proper alignment for debug/testing output.
  For example:
  byte[] bytes = System.Text.Encoding.UTF8.GetBytes("blog.cjvandyk.com rocks!");
bytes.Print();

• printf()

  Simple printf method for console output with color control. Both
  text color and background color is returned to previous state
  after the string has been written to console.
  For example:
  printf("Hello World!", ConsoleColor.Red, ConsoleColor.White);
  will output the string to console in red text on a white background.

• QueryStringToDictionary()

  Converts the current string (QueryString) to a dictionary of string
  objects for example:
  "?id=123&url=blog.cjvandyk.com&rating=awesome".QueryStringToDictionary()
  will return a dictionary with 3 entries thus:
  ["id"] = "123"
["url"] = "blog.cjvandyk.com"
["rating"] = "awesome"
  

• QueryStringToNameValueCollection()

  Converts the current string (QueryString) to a NameValueCollection
  a List of KeyValue pairs. The main difference from .QueryStringToDictionary()
  is that duplicates can be contained in the list for example:
  "?id=123&url=blog.cjvandyk.com&id=789".QueryStringToNameValueCollection()
  will return a dictionary with 3 entries thus:
  ["id"] = "123"
["url"] = "blog.cjvandyk.com"
["id"] = "789"
  

• Quote()

  Return the given string encased in requested quotes.
  Default is Constants.QuoteType.Double.
  For example:
  printf("https://blog.cjvandyk.com/sites/Rocks");
printf("https://blog.cjvandyk.com/sites/Rocks").Quote();
printf("https://blog.cjvandyk.com/sites/Rocks".Quote(
Constants.QuoteType.Single));
printf("https://blog.cjvandyk.com/sites/Rocks".Quote(
Constants.QuoteType.Double));
  will return
  https://blog.cjvandyk.com/sites/Rocks
"https://blog.cjvandyk.com/sites/Rocks"
'https://blog.cjvandyk.com/sites/Rocks'
"https://blog.cjvandyk.com/sites/Rocks"

• RemoveExtraSpace()

  Trims leading and trailing white space and then removes all extra
  white space in the given string returning a single spaced result.
  For example:
  " blog.cjvandyk.com rocks ! ".RemoveExtraSpace()
  will return
  "blog.cjvandyk.com rocks !"

• ReplaceTokens()

  Takes a given string object and replaces 1 to n tokens in the string
  with replacement tokens as defined in the given Dictionary of strings.

• Retry()

  Checks if a System.Net.WebException contains a "Retry-After" header.
  If it does, it sleeps the thread for that period (+ 60 seconds)
  before reattempting the HTTP call that caused the exception in the
  first place. If no "Retry-After" header exist, the exception is
  simply rethrown.
  For example:
  System.Net.HttpWebRequest request ...
Try
{
request.GetResponse();
}
Catch (System.Net.WebException ex)
{
ex.Retry(request);
}
  

• Save()

  Language extension providing a universal method to all objects
  that allows them to be serialized to disk.
  Does NOT require the [Serializable] property on object.
  For example:
  ComplexClass myClass = new ComplexClass(...<constructor parms>...);
myClass.Save("My file path");
  Use .Load() to reload objects back from disk.

• Set()

  _Language extension for properties. Use to set the value of the
  extension property in question.
  For example:
  Microsoft.SharePoint.Client client = new Microsoft.SharePoint.Client("https://blog.cjvandyk.com");
client.ExecutingWebRequest += ClientContext_ExecutingWebRequest;
client.Set("HeaderDecoration", "NONISV|Crayveon|MyApp/1.0");
  This allows the creation of the extension property "HeaderDecoration"
  which can be changed as needed. Later in the delegate method we
  refer back to the extension property value thus:
  private void ClientContext_ExecutingWebRequest(object sender, WebRequestEventArgs e)
{
e.WebRequestExecutor.WebRequest.UserAgent = (string)e.Get("HeaderDecoration");
}
  NOTE: We did not have to access the ClientContext class in order to
  retrieve the "HeaderDecoration" value since the extension was
  done against the System.Object class. As such, any object can
  be used to retrieve the extension property value, as long as
  you know the key value under which the property was stored and
  you know the type to which the returned value needs to be cast.
  A derived override method for Get() and Set() can be defined
  using specific class objects if finer controls is needed.
  

• SingleQuote()

sb.Append("abc1abc2abc3abc4");
sb.Substring(5);
  will return bc2abc3abc4
sb.Substring(5, 3);
  will return bc2
  Adds the FromHead/FromTail overloaded methods.
  FromHead returns the "length" of characters from the head of the given
  string.
  For example:
  sb.Substring(3, Constants.SubstringType.FromHead);
sb.Substring(5, Constants.SubstringType.FromHead);
sb.Substring(8, Constants.SubstringType.FromHead);
  will return
  abc
abc1a

sb.Substring(8, Constants.SubstringType.FromTail);
  will return
  bc4
3abc4
abc3abc4
  Adds the LeftOfIndex/RightOfIndex overloaded methods.
  LeftOfIndex returns the "length" of characters to the LEFT of the
  located index representing the "occurence"th match of the "index"
  string.
  For example:
  sb.Substring(5, "abc", Constants.SubstringType.LeftOfIndex, 0);
sb.Substring(5, "abc", Constants.SubstringType.LeftOfIndex, 1);
sb.Substring(5, "abc", Constants.SubstringType.LeftOfIndex, 2);
sb.Substring(5, "abc", Constants.SubstringType.LeftOfIndex, 3);

sb.Substring(5, "abc", Constants.SubstringType.RigthOfIndex, 1);
sb.Substring(5, "abc", Constants.SubstringType.RigthOfIndex, 2);
sb.Substring(5, "abc", Constants.SubstringType.RigthOfIndex, 3);
sb.Substring(5, "abc", Constants.SubstringType.RigthOfIndex, 4);
  will return
  ``
  1abc2
  `2abc3`
  `3abc4`
  `4`

• ToTimeZone()

  Convert given DateTime between different time zones with ease.
  For example:
  System.DateTime now = System.DateTime.UtcNow;
now.ToTimeZone(
Constants.TimeZone.UTC,
Constants.TimeZone.EasternStandardTime));
  will return the current UTC time as Eastern time.

• TrimLength()

  Returns part of the given System.Text.StringBuilder object
  tuncated to the requested length minus the length of the
  suffix.
  If the string is null or empty, it returns said value.
  If the string is shorter than the requested length, it returns
  the whole string.
  For example:
  "The Extensions.cs NuGet package rocks!".TrimLength(20)
  will return "The Extensions.cs..." while
  "The Extensions.cs NuGet package rocks!".TrimLength(20, "")
  will return "The Extensions.cs Nu" and
  "The Extensions.cs NuGet package rocks!".TrimLength(20, ">>")
  will return "The Extensions.cs >>"
  

• TrimStart()

  Trims a given string rather than just a character, from the start of
  the target string. The traditional Trim() only allowed char values
  to be trimmed. TrimStart() solves that limitation in an easier to
  fashion that using Substring().
  For example:
  "https://blog.cjvandyk.com".TrimStart("https://")
  will return
  "blog.cjvandyk.com"

• Validate()

  Makes quick work of conducting multiple types of validations on all
  parameters. It takes a parameter array of ErrorType and conducts
  the appropriate validation such as null checking, non-zero checking
  etc. against the parameter array passed.
  For example:
  Validate(Constants.ErrorTypeAll, amount, percent, years, frequency);
  will perform all defined error checks against the amount, percent,
  years and frequency parameters.

  • Add Logging.ConstructMessage().
    
  • Add Logging.ConsoleMessage().
    
  • Add Logging.EventLogMessage().
    
  • Add Logging.FileMessage().
    

• ValidateNoNulls()

  Makes quick work of null validating all parameters you pass to it.
  This method takes a variable number of parameters and validates that
  all parameters are not null. If a parameter is found to be null, a
  ArgumentNullException is thrown.
  For example:
  void MyMethod(string str, double dbl, MyClass cls)
{
Universal.ValidateNoNulls(str, dbl, cls);<br> ...Your code here...<br> }<br> You do not have to pass all parameters, but can instead do this:<br> void MyMethod(string str, double dbl, MyClass cls)<br> {<br> Universal.ValidateNoNulls(str, cls);
  ...Your code here...
}
  where we chose NOT to validate the double dbl in this case.

• Words()

  This method returns the number of words used in the given string
  object. For example:
  "This is my test".Words()
  will return 4 whereas
  "ThisIsMyTest".Words()
  will return 1.

• Wrn()

  Write a Warning message to active channels (console, event log, file)
  using the System.Logging class.
