String s = "1234567890123456789012345678901234567890";
            if (s.Length > 30)
                s = s.Remove(30);
//s is now 30 chars long - actually the if statement isn't actually required in this case

Why not? In the .NET Framework, strings are zero-based. The value of the startIndex parameter can range from zero to one less than the length of the string instance.
If startIndex specifies a position that is not within this string the ArgumentOutOfRangeException is thrown.

Good point, for some reason it didn't throw an exception when I tested it here without the if statement.  I've moved it into a button click event and now it does.  Hmmm?   (I didn't code it with an exception handler.)
