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

Using Microsoft's Northwind example database:

 System.Data.Entity.Design.PluralizationServices.PluralizationService.CreateService(new System.Globalization.CultureInfo("en-US"));

Singularize does not Singularize "Order_Details" It returns "Order_Details" with the s at the end. What is the work around?

Answer 2

I whipped one together based on the Rails pluralizer. You can see my blog post here, or on github here

output = Formatting.Pluralization(100, "sausage"); 

Answer 3

I cheated in Java - I wanted to be able to produce a correct string for "There were n something(s)", so I wrote the foll. little overloaded utility method:

static public String pluralize(int val, String sng) {
    return pluralize(val,sng,(sng+"s"));
    }

static public String pluralize(int val, String sng, String plu) {
    return (val+" "+(val==1 ? sng : plu)); 
    }

invoked like so

System.out.println("There were "+pluralize(count,"something"));
System.out.println("You have broken "+pluralize(count,"knife","knives"));

Answer 4

This page shows how to use PluralizationService of System.Data.Entity (.NET Framework 4.0)

Answer 5

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.
