I heard
LINQ is the new black, so here's my attempt using
LINQ:

private static
            Random random = new Random();
public static string RandomString(int
            length)
{
 const string chars =
            "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
 return new
            string(Enumerable.Repeat(chars, length)
 .Select(s =>
            s[random.Next(s.Length)]).ToArray());
}

(Note:
The use of the Random class makes this unsuitable
for anything security related, such as creating passwords or tokens. Use
the RNGCryptoServiceProvider class if you need a strong random
number generator.)
