如何用C＃制作Windows窗体应用程序以接收来自串行端口的数据

Question

我有这个（工作）代码，用于从串行端口接收数据并将其显示在c＃的控制台应用程序中。

#region Namespace Inclusions
using System;
using System.IO.Ports;
using System.Windows.Forms;
#endregion

namespace SerialPortExample
{
  class SerialPortProgram
  {
    // Create the serial port with basic settings
    private SerialPort port = new SerialPort("COM1",
      9600, Parity.None, 8, StopBits.One);

    [STAThread]
    static void Main(string[] args)
    { 
      // Instatiate this class
      new SerialPortProgram();
    }

    private SerialPortProgram()
    {
      Console.WriteLine("Incoming Data:");

      // Attach a method to be called when there
      // is data waiting in the port's buffer
      port.DataReceived += new 
        SerialDataReceivedEventHandler(port_DataReceived);

      // Begin communications
      port.Open();

      // Enter an application loop to keep this thread alive
      Application.Run();
    }

    private void port_DataReceived(object sender,
      SerialDataReceivedEventArgs e)
    {
  // Show all the incoming data in the port's buffer
  Console.WriteLine(port.ReadExisting());
    }
  }
}

但是，如何将这段代码转移到Windows窗体应用程序上呢？

我知道这是一个模糊的问题，但是如果可以的话，请为这个应用程序提供一些示例代码。

如果添加以下行来替换Application.Run语句，则应该可以使用了。 （删除原来的port.DataReceived行）

var frm = new Form { Height = 200, Width = 200 };
var txt = new TextBox {Dock = DockStyle.Fill, Multiline=true };
frm.Controls.Add(txt);
port.DataReceived += (sender, args) => { 
        if (txt.InvokeRequired)
        {
            txt.Invoke(new MethodInvoker(() => { 
                txt.Text += port.ReadExisting(); 
                }));
        } 
        else  
        {
           txt.Text += port.ReadExisting(); 
        }
   };
Application.Run( frm);
