C # Ping Class examples can be used to test the network, host response time, and so on.

This example is used to detect the normal communication between the host and the Ping class. Delay how many milliseconds, etc...

The complete code is as follows:

Introduction of namespaces:

Using System.Net.NetworkInformation;

Complete code:

namespace Pingexample {public partial class Form1:form {public Form1 () {Initializ
        Ecomponent (); } private void Btn_startping_click (object sender, EventArgs e) {this.lst_PingResult.Items.Cl
            Ear (); Remote server IP String ipstr = txt_IPAddress.Text.ToString ().
            Trim ();
            Construct Ping instance Ping Pingsender = new Ping ();
            Ping option to set pingoptions options = new PingOptions (); Options.
            Dontfragment = true;
            Test Data String = "Test Abcabc";
            byte[] buffer = Encoding.ASCII.GetBytes (data);
            Set timeout time int timeout = 120;
            Call the synchronous send method to send the data and save the return result to the pingreply instance pingreply reply = Pingsender.send (ipstr, timeout, buffer, options); if (reply. Status = = ipstatus.success {LST_PINGRESULT.ITEMS.ADD ("host address of reply:" + reply.)
     Address.tostring ());           LST_PINGRESULT.ITEMS.ADD ("Round Trip Time:" + reply.)
                Roundtriptime); LST_PINGRESULT.ITEMS.ADD (Live Time (TTL): + reply.
                OPTIONS.TTL); LST_PINGRESULT.ITEMS.ADD ("Control packet Fragmentation:" + reply.)
                Options.dontfragment); LST_PINGRESULT.ITEMS.ADD ("Buffer size:" + reply.)
            Buffer.length); else Lst_PingResult.Items.Add (reply.
        Status.tostring ());
 }
    }
}
