C# 客户端应用程序不会从 Linux TCP 服务器接收消息

>情况：1. LinuxTCP服务器2 视窗 C# 客户端应用程序

服务器从客户端接收消息，

但是当我尝试将消息从服务器发送到客户端时，没有任何反应。断开连接时出现错误：

"无法从传输连接读取数据：阻塞操作被对 WSACancelBlockingCall 的调用中断"，它指向字符串 Response = swRead.ReadLine（） --->行;

下面是客户端代码：

            while (connected)
            {
                // Show the messages in the log TextBox
                this.Invoke(new UpdateLogCallback(this.UpdateLog), new object[] {         swRead.ReadLine() });

        {

    }
    private void btnDisconnect_Click(object sender, EventArgs e)
    {
        char[] quit = new char[5];
        quit[0] = 'q'; quit[1] = 'w'; quit[2] = 'w'; quit[3] = 'w'; quit[4] = ''0';
        connected = false;

        client.Close();
    }
    public void OnApplicationExit(object sender, EventArgs e)
    {
        if (connected == true)
        {
            connected = false;
            swSend.WriteLine("qwww"); //proveri da li radi f-ja kako treba
            swSend.Flush();
            swSend.Close();
            client.Close();
        }
    }      
}

}

服务器端使用 read（） 函数接收消息并且工作正常，但是当它使用 write（） 发送时，C# 客户端不会收到消息。

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