带有windows窗体应用程序的C#socket服务器

我搜索了很多，但互联网上所有的例子都是控制台应用程序。我曾尝试使用windows窗体的控制台应用程序示例，但当我调用socket.start窗体时，它会冻结，状态更改为（而不是响应）。我也尝试了多个线程，但也不成功。如果可能的话，请给我一些建议

    }

谢谢。

您的应用程序将被阻止，直到按钮1\u单击返回

您需要生成一个工作线程来进行侦听。此外，不应将控件直接传递到工作线程。相反，您应该有一个回调，它将使用来自套接字通信的数据填充控件

查找有关后台工作人员的信息。这将使您到达需要的位置。

我也遇到了同样的问题，请按照我的服务器解决方案进行操作

对于客户，您需要设置一些控件； 两个文本视图（txtStatus和txtEnviar）和一个名为btnEnviar的按钮，就是它

您必须先运行服务器，然后才能运行客户端。如果需要停止客户端，请不要担心，您可以让服务器运行。

“我也尝试了多个线程，但也没有成功”-您是如何尝试的，您遇到了什么问题？在StartServer（）返回之前，应用程序将没有响应，这取决于接受传入连接并发回数据所需的时间。（默认情况下套接字是阻塞的）我在button1\u Click事件中调用了线程。问题是相同的表单冻结了。我尝试了你的解决方案，但也冻结了。我只是复制和粘贴代码，没有任何更改
