"Please mark your answers with an acceptance to put the code in the Codeplex project."

Why? All the Stuff on this site under CC-by-sa-2.5, so just put your Extension overflow Project under the same license and you can freely use it.

Anyway, here is a String.Reverse function, based on this question.

/// 

/// Reverse a String
/// 
/// The string to Reverse
/// The reversed String
public static string Reverse(this string input)
{
    char[] array = input.ToCharArray();
    Array.Reverse(array);
    return new string(array);
}
