使用C#调用外部Ping命令获取网络连接情况

using System;

using System.Diagnostics;

 

namespace ZZ

{

     class ZZConsole

     {

         [STAThread]
         static void Main(string[] args)

         {   

              string ip = "192.168.1.1";

              string strRst = CmdPing(ip);

              Console.WriteLine(strRst);

              Console.ReadLine();

         }

 

         private static string CmdPing(string strIp)

         {
