Socket单客户端/服务器连接，服务器可以发送多次，客户端只能发送一次

Socket single client/server connection, server can send multiple times, client can only once(Socket单客户端/服务器连接，服务器可以发送多次，客户端只能发送一次)

问题描述

我编写了一个客户端和服务器应用程序，我需要用它来连接我用 C# 制作的跳棋游戏.我已经让客户端和服务器连接，服务器可以重复发送客户端消息以更新标签，但是当客户端尝试发送消息时它会抛出错误

I have written a client and server application that I need to use to connect a checkers game I made in C#. I have got the client and server to connect and the server can repeatedly send the client messages to update a label but when the client tries to send a message it throws the error

发送或接收数据的请求被拒绝，因为套接字未连接并且(当使用 sendto 调用在数据报套接字上发送时)没有提供地址."

"A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket using a sendto call) no address was supplied."

到目前为止，这是我的客户端和服务器.

Here is my client and server so far.
