C#客户端应用程序不'；无法从linux tcp服务器接收消息

情况： 1.Linux TCP服务器 2 Windows C#客户端应用程序

服务器从客户机接收消息，但当我尝试从服务器向客户机发送消息时，什么也没有发生。当我断开连接时，会出现错误：

“无法从传输连接读取数据：对WSACancelBlockingCall的调用中断了阻塞操作。”它指向行---->string Response=swRead.ReadLine（）

以下是客户端代码：

            swSend.WriteLine("qwww"); //proveri da li radi f-ja kako treba
            swSend.Flush();

            swSend.Close();

}

服务器端使用read（）函数接收消息，工作正常，但当使用write（）函数发送消息时，C#客户端不会接收消息。

只有一件事（可能还有其他问题）： 您有一个

已连接的

变量，在启动侦听线程后，将该变量的值设置为

true

。线程中的循环甚至不会运行一次

---

Linux端是将

\r\n

作为其行的结尾发送，还是仅发送

\n

？

thrMessag = new Thread(new ThreadStart(ReceiveMessages));   
thrMessag.Start();              
connected = true; //here is your first bug, should come before the previos line
