这个例子包括了这个控件几乎所有的操作,非常有参考价值.serialPort是在.net framework2.0中才有的东西,感觉这个东西和MSCOMM很相似。 使用SerialPort类设计串口通讯Windows Mobile 6下使用

•

程... serialPo... • 传感器(c#2.0)serialPort串口通...

最近读者：

C＃：

1) 从工具箱选择SerialPort控件添加到窗体上，命名为SpCom 。 2) 设置通讯端口号及波特率、数据位、停止位和校验位。

SpCom.PortName = \"COM1\"; SpCom.BaudRate = 9600;

SpCom.Parity = IO.Ports.Parity.None;

SpCom.DataBits = 8;

SpCom.StopBits = IO.Ports.StopBits.One;

3) 发送数据

SpCom.Write(TextSendData.Text) ; 4) 添加接受事件

private void serialPortCom2_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e)

5) 读取数据

String strT;

strT=SpCom.ReadExisting();

mycom是串口通信类，在本blog前一篇中有完整代码。( C#串口通信编程类(修改版) )

下面是串口通讯测试程序的源代码，将mycom类放在此项目中

可以实现简单的串口通信，希望读者能通过这个程序对串口通信过程有一个初步的了解：
