串口接收发送WinForm实现之C#设计笔记(九)

1、using如下
using System;
using System.Text;
using System.Windows.Forms;
using System.Collections;
using System.IO.Ports;
using System.IO;
2、页面打开时，自动识别连接串口设计
private void dataTrans_Load(object sender, EventArgs e)
{
string[] portList = SerialPort.GetPortNames();
comboBox_serialNo.Items.Clear();
for (int i = 0; i < portList.Length; i++)
{
string name = portList[i];
comboBox_serialNo.Items.Add(name);
}
mySerialPort.DataReceived += new SerialDataReceivedEventHandler(DataReceive_Method);// new SerialDataReceivedEvenHandler(DataReceive_Method);
}
3、定义串口接收订阅事件实现方法
private void DataReceive_Method(object sender, SerialDataReceivedEventArgs e)
{
//serialReadString = mySerialPort.ReadExisting();
byte [] tempdata=new byte[mySerialPort.ReadBufferSize];
// Console.WriteLine(“read size:{0
