Answer 1

拖放timer控件，在Tictk事件里写:this.textBox2.Text = "";
            ProcessStartInfo start = new ProcessStartInfo("Ping.exe");
            start.Arguments =this.textBox1.Text;
            start.CreateNoWindow = true;
            start.RedirectStandardOutput = true;
            start.RedirectStandardInput = true;
            start.UseShellExecute = false;
            Process p = Process.Start(start);
            StreamReader reader = p.StandardOutput;
            string line = reader.ReadLine();
            while (!reader.EndOfStream)
            {
                textBox2.AppendText(line + "\n");
                line = reader.ReadLine();
            }
            p.WaitForExit();
            p.Close();
            reader.Close();

代码有点长
用里面的pingH

不建议使用2楼的方法 第一 杀毒软件会叫 第二 占资源 第三 慢
看看代码吧
在此：        private void timerping_Tick(object sender, EventArgs e)
        {
            string who = gateway .ToString ();            AutoResetEvent waiter = new AutoResetEvent(false);            Ping pingSender = new Ping();
            pingSender.PingCompleted += new PingCompletedEventHandler(PingCompletedCallback);
            string data = "NCV_netcheck";
            byte[] buffer = Encoding.ASCII.GetBytes(data);
            int timeout = timerping .Interval ;
            PingOptions options = new PingOptions(64, true);
            pingSender.SendAsync(who, timeout, buffer, options, waiter);
        }
        public void PingCompletedCallback(object sender, PingCompletedEventArgs e)
        {
            string gatestr="";
            long delaygate = 100;
            if (e.Cancelled)
            {
               gatestr  = "Ping canceled.";
                ((AutoResetEvent)e.UserState).Set();
            }
            if (e.Error != null)
            {
                gatestr = "N/A";
                gatestr = e.Error.ToString();
                ((AutoResetEvent)e.UserState).Set();
            }            PingReply reply = e.Reply;            
            if (reply.Status == IPStatus.Success)
            {
                delaygate = reply.RoundtripTime+1;
                gatestr = delaygate.ToString();
                if (delaygate > 99) delaygate = 100;
                this.barGW.Value = (int)delaygate+2;
            }
            ((AutoResetEvent)e.UserState).Set();
            this.gate_way.Text = gatestr+"ms";   
        }gatestr就是延迟了

做个timer重复  重复事件不要小于超时事件 不然你会发现你机子在飞奔（100％）运行ping网关
