网上有很多用C#调用cmd的方法，大致如下：

private void ExecuteCmd(string command)
{
Process p = new Process();
p.StartInfo.FileName = "cmd.exe";
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardInput = true;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.CreateNoWindow = true;
p.Start();
p.StandardInput.WriteLine(command);
p.StandardInput.WriteLine("exit");
p.WaitForExit();
this.textBox1.Text=textBox1.Text+ p.StandardOutput.ReadToEnd();
p.Close();
}

上面代码有几个不足，一是必须要exit那一句，否则就会死循环。再就是每次执行Execute执行cmd后，都必须等到cmd执行完且cmd.exe进程退出，才能读到结果。有时候这样会让

 我们的应用程序失去操作的连续性。

事实上，通过两个线程，一个访问输入管道，一个访问输出管道，可以很容易实现持续性的效果，

下面是一个Console程序：

using System;  
using System.Collections.Generic;  
using System.Linq;  
using System.Text;  
using System.Threading;  
using System.Diagnostics;  namespace cmdtest  
{  class Program  {  public static string cmd_str;  public static string cmd_outstr;  public static Process p = new Process();  static void Main(string[] args)  {  p.StartInfo.FileName = "cmd.exe";  p.StartInfo.UseShellExecute = false;  p.StartInfo.RedirectStandardInput = true;  p.StartInfo.RedirectStandardOutput = true;  p.StartInfo.RedirectStandardError = true;  p.StartInfo.CreateNoWindow = true;  p.Start();  cmd_str = "";  cmd_outstr = "";  Thread t1 = new Thread(new ThreadStart(DoCmdThread));  t1.Start();  Thread t2 = new Thread(new ThreadStart(OutCmdThread));  t2.Start();  while(true)  {  cmd_str = Console.ReadLine();  Thread.Sleep(10);  if (cmd_str == "exit")  break;  }  }  public static void DoCmdThread()  {  while (true)  {  if (cmd_str == "exit")  break;  if (cmd_str != "")  {  p.StandardInput.WriteLine(cmd_str);  //p.StandardInput.WriteLine("cd");  cmd_str = "";  }  Thread.Sleep(1);  }  }  public static void OutCmdThread()  {  while (true)  {  if (cmd_str == "exit")  {  p.StandardInput.WriteLine("exit");  p.WaitForExit();  p.Close();  break;  }  cmd_outstr = p.StandardOutput.ReadLine();  while(cmd_outstr != "")  {  Console.WriteLine(cmd_outstr);  cmd_outstr = p.StandardOutput.ReadLine();  }  char[] ch = new char[256];  int c = p.StandardOutput.Read(ch, 0, 256);  if (c > 0)  {  Console.Write(ch,0,c);  }  Thread.Sleep(1);  }  }  }  
}
