Is there any algorithm in c# to singularize - pluralize a word?

Question

Is there any algorithm in c# to singularize - pluralize a word (in english) or does exist a .net library to do this (may be also in different languages)?

Answer 1

Not much documentation from MSDN on the specific usage of the PluralizationService class so here is a unit test class (NUnit) to show basic usage. Notice the odd test case at the bottom that shows the service isn't perfect when it comes to non-standard plural forms.

[TestFixture]
public class PluralizationServiceTests
{
    [Test]
    public void Test01()
    {
        var service = PluralizationService.CreateService(CultureInfo.CurrentCulture);

        Assert.AreEqual("tigers", service.Pluralize("tiger"));
        Assert.AreEqual("processes", service.Pluralize("process"));
        Assert.AreEqual("fungi", service.Pluralize("fungus"));

        Assert.AreNotEqual("syllabi", service.Pluralize("syllabus")); // wrong pluralization
    }
}
