在TCPserver没有应答的情况下socketTcp重连异常，导致致命性错误

OtherControl,114行

private void but_tcpSend_Click(object sender, EventArgs e)
        {
            try
            {
                var command = DataConvert.StringToByteArray(txt_tcpmsg.Text, false);
                socketTcp.Send(command);
                var msg = SocketRead(socketTcp, 4096);
                AppendText(msg.ByteArrayToString());
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
                //重新连接
                socketTcp?.Close();
                socketTcp.Connect(new IPEndPoint(IPAddress.Parse(txt_tcpip.Text?.Trim()), int.Parse(txt_tcpport.Text?.Trim())));
            }
        }

应该再包一层try 或者用非阻塞的方式Receive
