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 |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

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