| <!-- | ||
| Microsoft ResX Schema | ||
| Version 2.0 | ||
| The primary goals of this format is to allow a simple XML format | ||
| that is mostly human readable. The generation and parsing of the | ||
| various data types are done through the TypeConverter classes | ||
| associated with the data types. | ||
| Example: | ||
| ... ado.net/XML headers & schema ... | ||
| <resheader name="resmimetype">text/microsoft-resx</resheader> | ||
| <resheader name="version">2.0</resheader> | ||
| <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader> | ||
| <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader> | ||
| <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data> | ||
| <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data> | ||
| <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64"> | ||
| <value>[base64 mime encoded serialized .NET Framework object]</value> | ||
| </data> | ||
| <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64"> | ||
| <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value> | ||
| <comment>This is a comment</comment> | ||
| </data> | ||
| There are any number of "resheader" rows that contain simple | ||
| name/value pairs. | ||
| Each data row contains a name, and value. The row also contains a | ||
| type or mimetype. Type corresponds to a .NET class that support | ||
| text/value conversion through the TypeConverter architecture. | ||
| Classes that don't support this are serialized and stored with the | ||
| mimetype set. | ||
| The mimetype is used for serialized objects, and tells the | ||
| ResXResourceReader how to depersist the object. This is currently not | ||
| extensible. For a given mimetype the value must be set accordingly: | ||
| Note - application/x-microsoft.net.object.binary.base64 is the format | ||
| that the ResXResourceWriter will generate, however the reader can | ||
| read any of the formats listed below. | ||
| mimetype: application/x-microsoft.net.object.binary.base64 | ||
| value : The object must be serialized with | ||
| : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter | ||
| : and then encoded with base64 encoding. | ||
| mimetype: application/x-microsoft.net.object.soap.base64 | ||
| value : The object must be serialized with | ||
| : System.Runtime.Serialization.Formatters.Soap.SoapFormatter | ||
| : and then encoded with base64 encoding. | ||
| mimetype: application/x-microsoft.net.object.bytearray.base64 | ||
| value : The object must be serialized into a byte array | ||
| : using a System.ComponentModel.TypeConverter | ||
| : and then encoded with base64 encoding. | ||
