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 |Rb S@+ private void button1_Click(object sender, EventArgs e) hIurY { LJaP%-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&t2 sbuilder.Append(string.Format("Time to live: {0} ", reply.Options.Ttl)); Z fiVS 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#]- } #Z3
;oQ }[nextpage] 9uV"-T
, 也可以做异步的处理，修改button1_click,并添加PingCompletedCallBack方法 U f!95"Hu private void button1_Click(object sender, EventArgs e) zGqudcx$5 { uo\ P2"_& Ping p1 = new Ping(); )N$xY%^` p1.PingCompleted += new PingCompletedEventHandler(this.PingCompletedCallBack);//设置PingCompleted事件处理程序 _<?j&> p1.SendAsync(this.textBox1.Text, null); =?$YZo1 } sHE?U(hm7 private void PingCompletedCallBack(object sender, PingCompletedEventArgs e) CB { F)GAQSBqt if (e.Cancelled) .]@5RVe { v+EmLb)p listBox1.Items.Add("Ping Canncel"); i*Hm0 9c return; [=V 9N } 5v6qSSH if (e.Error != null) '{k16/jT { ^CLoTsV7: listBox1.Items.Add(e.Error.Message); (3E?Gz#p return; "CTAgf?5 } Z*uZ\=o}1 StringBuilder sbuilder; A ;je=T PingReply reply = e.Reply; %ok$l>)H if (reply.Status == IPStatus.Success) k5O&a #,ra { FX Qi 5 sbuilder = new StringBuilder(); L3\@CH': sbuilder.Append(string.Format("Address: {0} ", reply.Address.ToString())); 2l:?SAIO. sbuilder.Append(string.Format("RoundTrip time: {0} ", reply.RoundtripTime));
