c#下实现ping操作实用程序代码

      这里我写的是一个窗体程序。首先添加textbox,listbox,button控件，其中textbox录入域名或IP，listbox显示结果. ( gLp:V4Zj
      在button1_click事件键入 | R b S@ +
      private void button1_Click(object sender, EventArgs e) h Iur Y
      { L JaP%- V0
      Ping p1 = new Ping(); //只是演示，没有做错误处理 hdc S&\
      PingReply reply = p1.Send(this.textBox1.Text);//阻塞方式 displayReply(reply); //显示结果 } private void displayReply(PingReply reply) //显示结果 3Te7R lJa
      { =7/J4(uwd
      StringBuilder sbuilder ; zw r] 1*|&
      if (reply.Status == IPStatus.Success) 0a( " <
      { ~Gv&G / 4
      sbuilder = new StringBuilder(); q "N] bG
      sbuilder.Append(string.Format("Address: {0} ", reply.Address.ToString ())); b"_[ a. ]
      sbuilder.Append(string.Format("RoundTrip time: {0} ", reply.RoundtripTime)); Z1[ay&t 2
      sbuilder.Append(string.Format("Time to live: {0} ", reply.Options.Ttl)); Z f i V S
      sbuilder.Append(string.Format("Don't fragment: {0} ", reply.Options.DontFragment)); ;_, >}&)da
      sbuilder.Append(string.Format("Buffer size: {0} ", reply.Buffer.Length)); " f=$ Ubx
      listBox1.Items.Add(sbuilder.ToString()); {qdM}Ot#]-

      也可以做异步的处理，修改button1_click,并添加PingCompletedCallBack方法 U f!95 "Hu
