关机代码用C#调用API编写的哈哈！！！怎样都可以强制关机

一般的聊天程序都是使用socket方式通讯的。对于一个聊天程序来说一般是一个服务器用来中转消息，然后是多个客户端通过连接服务器来消息交换。(General chat programs are using the socket mode of communication. For a chat program, it is generally a server used to relay the message, then multiple clients to connect to the server through the exchange of messages.)

说明：  　黑白棋的棋盘是一个有8*8方格的棋盘。下棋时将棋下在空格中间，而不是像围棋一样下在交叉点上。开始时在棋盘正中有两白两黑四个棋子交叉放置，黑棋总是先下子。 　 下子的方法:把自己颜色的棋子放在棋盘的空格上，而当自己放下的棋子在横、竖、斜八个方向内有一个自己的棋子，则被夹在中间的全部翻转会成为自己的棋子。并且，只有在可以翻转棋子的地方才可以下子。(The chessboard of black and white is a chessboard with 8 * 8 squares. When playing chess, the game is played in the middle of the space, not at the intersection like go. At the beginning, there are two white, two black and four pieces in the center of the board. Black chess always comes first. Sub method: put the pieces of your own color on the space of the board, and when the pieces you put down have one of your own pieces in the horizontal, vertical and oblique directions, all the pieces in the middle will be turned into your own pieces. In addition, only in the place where the chess pieces can be flipped can they be flipped.)
