Related Links:

Write a recursive method named RepeatString that accepts a string and an integer n as parameters and that returns the string concatenated n times. For example, the call of RepeatString("hello", 3) returns "hellohellohello". Do not use any loops; you must use recursion.

Constraints: Your method should throw an ArgumentException if passed any negative value for n. You are not allowed to construct any structured objects other than strings (no array, List, Scanner, etc.) and you may not use any loops to solve this problem; you must use recursion.

Method: Write a C# method as described, not a complete program or class.
