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。
