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

Answer 1

Another flavor:

/// 

/// Extension methods for numbers
/// 
public static class NumericExtensions
{
    /// 

    /// Adds the ordinal indicator to an integer
    /// 
    /// The number
    /// The formatted number
    public static string ToOrdinalString(this int number)
    {
        // Numbers in the teens always end with "th"

        if((number % 100 > 10 && number % 100 < 20))
            return number + "th";
        else
        {
            // Check remainder

            switch(number % 10)
            {
                case 1:
                    return number + "st";

                case 2:
                    return number + "nd";

                case 3:
                    return number + "rd";

                default:
                    return number + "th";
            }
        }
    }
}
