VB string.left and string.right as C# Extension methods on string

[mmsaffari]

Perhaps these 2 tiny methods I'm sharing here come handy to someone.

		public static string Left(this string input, int length) {
			string result = input;
			if (input != null && input.Length > length) {
				result = input.Substring(0, length);
			}
			return result;
		}

		public static string Right(this string input, int length) {
			string result = input;
			if (input != null && input.Length > length) {
				result = input.Substring(input.Length - length, length);
			}
			return result;
		}
