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

@nickf: Here is the PHP function in C#:

public static string Ordinal(int number)
{
    string suffix = String.Empty;

    int ones = number % 10;
    int tens = (int)Math.Floor(number / 10M) % 10;

    if (tens == 1)
    {
        suffix = "th";
    }
    else
    {
        switch (ones)
        {
            case 1:
                suffix = "st";
                break;

            case 2:
                suffix = "nd";
                break;

            case 3:
                suffix = "rd";
                break;

            default:
                suffix = "th";
                break;
        }
    }
    return String.Format("{0}{1}", number, suffix);
}
