// 状态提示追加
private void AppendStatus(string message)

}
添加输入验证：private bool ValidateIPPort
{
if (!IPAddress.TryParse(txtIP.Text, out _)) {
MessageBox.Show("无效IP地址");
return false;
}
if (!int.TryParse(txtPort.Text, out _)) {
MessageBox.Show("无效端口号");
return false;
}
return true;
}
添加连接状态检查：private void SendCommand(byte command)
{
if (!isConnected) {
AppendStatus("请先建立连接");
return;
}
// ...原有发送逻辑
}
