Question

How can i get below mentions date format in c#.

• For 1-Nov-2010 it should be display as : 1st November

Can we do using any date format or make a custom function that returns for 1 -> 'st', 2-> 'nd' 3-> 'rd', any date no -> 'th'.

Answer 1

The following code is based on that answer that generates an ordinal from an integer:

public static string ToOrdinal(int number)
{
    switch(number % 100)
    {
        case 11:
        case 12:
        case 13:
            return number.ToString() + "th";
    }

    switch(number % 10)
    {
        case 1:
            return number.ToString() + "st";
        case 2:
            return number.ToString() + "nd";
        case 3:
            return number.ToString() + "rd";
        default:
            return number.ToString() + "th";
    }
}

Than you can generate your output string:

public static string GenerateDateString(DateTime value)
{
    return string.Format(
        "{0} {1:MMMM}",
        ToOrdinal(value.Day),
        value);            
}
