C# 虛擬串口通信

將主埠COM8拆分成 COM1和COM2兩個虛擬埠

 COM8接收的消息會傳遞給COM1和COM2

SerialPort spSend;//spSend,spReceive用虛擬串口連接，它們之間可以相互傳輸數據。spSend發送數據

SerialPort spReceive; //spReceive接受數據

private delegate void MyDelegate(string indata); //委托，處理接收的數據

private MyDelegate showDelegate = null;

 showDelegate = new MyDelegate(show);

 spReceive = new SerialPort("COM1", 19200, Parity.None, 8, StopBits.One);

spReceive.DataReceived += new SerialDataReceivedEventHandler(DataReceivedHandler); //虛擬串口監聽接收消息監聽事件，該事件並不在主線程運行
spReceive.Open();//打開串口，工作完成時務必關閉串口

  void show(string indata)

{

//處理COM1接收的消息

}

private void DataReceivedHandler(object sender, SerialDataReceivedEventArgs e)

{

 SerialPort sp = (SerialPort)sender;

this.Invoke(showDelegate, new object[] { sp.ReadExisting() });

}
