C#实现Ping的方法小结

本文实例总结了C#实现Ping的方法。分享给大家供大家参考。具体如下：

方法一：

class Program
{
 public string cmdPing(string strIP)
 {
   Process myProcess = new Process();
   myProcess.StartInfo.FileName = "cmd.exe";
   myProcess.StartInfo.UseShellExecute = false;
   //要重定向 IO 流，Process 对象必须将 UseShellExecute 属性设置为 False。
   myProcess.StartInfo.RedirectStandardOutput = true;
   myProcess.StartInfo.RedirectStandardInput = true;
   myProcess.StartInfo.RedirectStandardError = true;
   string pingstr;
   myProcess.Start();
   myProcess.StandardInput.WriteLine("ping " + strIP);
   myProcess.StandardInput.WriteLine("exit");
   string strRst = myProcess.StandardOutput.ReadToEnd();
   if (strRst.IndexOf("(0% loss)") != -1)
   pingstr = "连接";
   else if (strRst.IndexOf("Destination host unreachable.") != -1)
   pingstr = "无法到达主机";
   else if (strRst.IndexOf("UnKonw host") != -1)
   pingstr = "无法解析主机";
   else
   pingstr = strRst;
   myProcess.Close();
   return pingstr;
 }
 static void Main(string[] args)
 {
  Program myProgram = new Program();
  string returnString = myProgram.cmdPing("127.0.0.1");
  Console.WriteLine(returnString);
  Console.ReadLine();
 }
}

方法二：

static void Main(string[] args)
{
  Ping ping = new Ping();
  PingOptions pingOption = new PingOptions(50, true);
  string data = " you are a such a beautiful girl";
  byte[] buffer = Encoding.ASCII.GetBytes(data);
  PingReply pingReply = ping.Send("192.168.1.100", 20, buffer);
  if (pingReply.Status == IPStatus.Success)
  {
   Console.WriteLine("address:{0}", pingReply.Address.ToString());
   Console.WriteLine("Round Trip time {0}", pingReply.RoundtripTime);
   Console.WriteLine("time to live:{0}", pingReply.Options.Ttl);
   Console.WriteLine("Do not to fragement:{0}", pingReply.Options.DontFragment);
  }
  Console.ReadKey();
}

希望本文所述对大家的C#程序设计有所帮助。
