Is there an easy way in .NET to get “st”, “nd”, “rd” and “th” endings for numbers? [duplicate]

Answer 1

This has already been covered but I'm unsure how to link to it. Here is the code snippit:

    public static string Ordinal(this int number)
    {
        var ones = number % 10;
        var tens = Math.Floor (number / 10f) % 10;
        if (tens == 1)
        {
            return number + "th";
        }

        switch (ones)
        {
            case 1: return number + "st";
            case 2: return number + "nd";
            case 3: return number + "rd";
            default: return number + "th";
        }
    }

FYI: This is as an extension method. If your .NET version is less than 3.5 just remove the this keyword

[EDIT]: Thanks for pointing that it was incorrect, that's what you get for copy / pasting code :)
