异步获取CMD命令行输出内容

当控制台命令使用process.Start(); 后可以直接显示输出内容，当然它是异步显示的不用等程序结束。代码如下:

using  System;
using  System.Collections.Generic;
using  System.ComponentModel;
using  System.Data;
using  System.Drawing;
using  System.Linq;
using  System.Text;
using  System.Windows.Forms;
using  System.Diagnostics;

namespace  testApplication1
{
     public   partial   class  Form1 : Form
    {
         public  Form1()
        {
            InitializeComponent();
        }

         private   void  button1_Click( object  sender, EventArgs e)
        {
             using  (Process process  =   new  System.Diagnostics.Process())  
            { 
                process.StartInfo.FileName  =   " ping " ; 
                process.StartInfo.Arguments  =   " 127.0.0.1 -t " ;
                process.StartInfo.UseShellExecute  =   false ;
                process.StartInfo.CreateNoWindow  =   true ;  
                process.StartInfo.RedirectStandardOutput  =   true ; 
                
                process.Start(); 
                process.BeginOutputReadLine();  
                process.OutputDataReceived  +=   new  DataReceivedEventHandler(process_OutputDataReceived);  
            }  
        }

         private   void  process_OutputDataReceived( object  sender, DataReceivedEventArgs e) 
        {
             if  ( ! string .IsNullOrEmpty(e.Data))
                 this .AppendText(e.Data  +  Environment.NewLine);   
        }
         public   delegate   void  AppendTextCallback( string  text);  
        
         public   void  AppendText( string  text)  
        { 
             if  ( this .textBox1.InvokeRequired)  
            {  
                AppendTextCallback d  =   new  AppendTextCallback(AppendText);  
                 this .textBox1.Invoke(d, text); 
            } 
             else  
            {  
                 this .textBox1.AppendText(text);                  
            } 
        }  
    }
}

 

程序是一个ping -t的示例：
