.net里的System.Net.NetworkInformation.Ping的简单使用

private void button_Ping_Click(object sender, EventArgs e)
        {
            Ping pingSender = new Ping();
            PingOptions options = new PingOptions();
            // Use the default Ttl value which is 128,
            // but change the fragmentation behavior.
            options.DontFragment = true;
            // Create a buffer of 32 bytes of data to be transmitted.
            string data = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
            byte[] buffer = Encoding.ASCII.GetBytes(data);
            int timeout = 3000;
            PingReply reply = pingSender.Send(textBox_TargetHost.Text.Trim(), timeout, buffer, options);
            if (reply.Status == IPStatus.Success)
            {
                Console.WriteLine("Address: {0}", reply.Address.ToString());
                Console.WriteLine("RoundTrip time: {0}", reply.RoundtripTime);
                Console.WriteLine("Time to live: {0}", reply.Options.Ttl);
                Console.WriteLine("Don't fragment: {0}", reply.Options.DontFragment);
                Console.WriteLine("Buffer size: {0}", reply.Buffer.Length);
            }
            else
            {
                Console.WriteLine(string.Format("[{0}] Ping timeout!",DateTime.Now.ToString()));
            }
        }
