創建一個事件，以便在串行端口上數據可用時

Question

我是C＃和.Net編程的新手，但我想知道是否有辦法在串行端口上有數據時創建事件？

我想你需要的例子可以找到here。
我寫的例子：

using System; 
using System.IO.Ports; 

class PortDataReceived 
{ 
    public static void Main() 
    { 
     SerialPort mySerialPort = new SerialPort("COM1"); 

     mySerialPort.BaudRate = 9600; 
     mySerialPort.Parity = Parity.None; 
     mySerialPort.StopBits = StopBits.One; 
     mySerialPort.DataBits = 8; 
     mySerialPort.Handshake = Handshake.None; 

     mySerialPort.DataReceived += new SerialDataReceivedEventHandler(DataReceviedHandler); 

     mySerialPort.Open(); 

     Console.WriteLine("Press any key to continue..."); 
     Console.WriteLine(); 
     Console.ReadKey(); 
     mySerialPort.Close(); 
    } 

    private static void DataReceviedHandler(
         object sender, 
         SerialDataReceivedEventArgs e) 
    { 
     SerialPort sp = (SerialPort)sender; 
     string indata = sp.ReadExisting(); 
     Console.WriteLine("Data Received:"); 
     Console.Write(indata); 
    } 
}
