Ping on server with C#

Question

Is there a . Net class with the ping feature? I have the server IP in a string type attribute and would like to drip the server to see if it is online or offline. Does anyone know ?

Answer 1

There is this class Ping

public class PingExample
    {
        // args[0] can be an IPaddress or host name.
        public static void Main (string[] args)
        {
            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 = 120;
            PingReply reply = pingSender.Send (args[0], 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);
            }
        }
    }

Updating. There is a simpler constructor for Send: Link

There is the Ping class, example of use:

public static bool pingServidor(string nameOrAddress)
{
    bool pingable = false;
    Ping pinger = new Ping();
    PingReply reply = pinger.Send(nameOrAddress);
    return reply.Status == IPStatus.Success;
}
