Tic Tac Toe (Game) [www.ScriptHood.com]

Tic-Tac-Toe, is a classic game for two players, X and O, who take turns marking the spaces in a 3×3 grid. The X player usually goes first. The player who succeeds in placing three respective marks in a horizontal, vertical, or diagonal row wins the game.Below are the source code of this game which I wrote in C#.
