Inflector is a simple lightweight .NET netstandard class library enabling you to pluralize, singularize, titleize (...) words in a specific culture.
Singular to plural word conversion.
// using extension methods
Inflector.SetDefaultCultureFunc = () => Thread.CurrentThread.CurrentUICulture; // must be setled before using extension methods
...
var cats = "cat".Pluralize(); // produces "cats" (assuming the default culture setled early is english)
// using Inflector class
var inflector = new Inflector(new CultureInfo("en"));
var cats = inflector.Pluralize("cat"); // produces: catsPlural to singular word conversion.
// using extension methods
Inflector.SetDefaultCultureFunc = () => Thread.CurrentThread.CurrentUICulture; // must be setled before using extension methods
...
var homem = "homens".Singularize(); // produces: homem (assuming the default culture setled early is portuguese)
// using Inflector class
var inflector = new Inflector(new CultureInfo("pt"));
var homem = inflector.Singularize("homens"); // produces: homemCapitalizes the first char and lowers the rest of the string.
var sentence = "the quick brown FOX jumps over the lazy dog".Capitalize();
// produces: The quick brown fox jumps over the lazy dogLowers the first char and leaves the remaining text unchanged.
var sentence = "The quick brown FOX jumps over the lazy dog".Uncapitalize();
// produces: the quick brown FOX jumps over the lazy dogTBD
