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

I've created a tiny library for this in .net (C#), called Pluralizer (unsurprisingly).

It's meant to work with full sentences, something like String.Format does.

It basically works like this:

var target = new Pluralizer();
var str = "There {is} {_} {person}.";

var single = target.Pluralize(str, 1);
Assert.AreEqual("There is 1 person.", single);

// Or use the singleton if you're feeling dirty:
var several = Pluralizer.Instance.Pluralize(str, 47);
Assert.AreEqual("There are 47 people.", several);

It can also do way more than that. Read more about it on my blog. It's also available in NuGet.
