关于TCP 中 networksteam实例read如何关闭的问题

Question

接标题，刚开始客户端networkstream.read函数一直执行，无法停止，上网查了说在服务器端传完后要调用networkstream.close()，但调用这个函数后客户端又显示说：已经中止了连接，无法传送数据了。
所以我想问各位好友：
客户端的read如何在接收完数据后停止运行
谢谢你们了C# TCP

客户端相关代码如下
        private void ReceiveMessage()
        {
           
            while(!isExit)
            {
                if (this.InvokeRequired)
                {
                    MessageBox.Show("Invoke");
                    this.Invoke(new ReceiveMessageDelegate(ReceiveMessage));
                }
                else 
                {
                    MessageBox.Show("进入Receive");
                    NetworkStream ReceiveFromServer = client.GetStream();
                    ReceiveFromServer.ReadTimeout = 1000;
                    ReceiveFromServer.WriteTimeout = 1000;
                    byte[] buffer = new byte[8192];
                    int bytesRead;
                    string message = null;
                    try
                    {
                        while (ReceiveFromServer.DataAvailable)
                        {
                                bytesRead = ReceiveFromServer.Read(buffer, 0, 255);
                                message = Encoding.UTF8.GetString(buffer, 0, bytesRead);
                                MessageBox.Show(message);
                                rtxContent.AppendText("服务器说："+message + "\n");
                        } 
                    }
                    catch (Exception ex)
                    {
                        MessageBox.Show("从服务器读取数据错误："+ex.Message);
                    }
                }
            }
            Application.Exit();
        }
