PingReply.Status Property

Gets the status of an attempt to send an Internet Control Message Protocol (ICMP) echo request and receive the corresponding ICMP echo reply message.

Namespace: System.Net.NetworkInformation
Assembly: System (in system.dll)

'Declaration
Public ReadOnly Property Status As IPStatus
'Usage
Dim instance As PingReply
Dim value As IPStatus

value = instance.Status

/** @property */
public IPStatus get_Status ()

public function get Status () : IPStatus

Not applicable.

Property Value

An IPStatus value indicating the result of the request.

If the value of Status is not Success, you should not use the values returned by the RoundtripTime, Options or Buffer properties. The RoundtripTime and Buffer properties will return zero, and the Options property will return a null reference (Nothing in Visual Basic).

The following code example demonstrates using Ping class to send an ICMP echo request synchronously and display the response.

using System;
using System.Net;
using System.Net.NetworkInformation;
using System.Text;

namespace Examples.System.Net.NetworkInformation.PingTest
{
    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);
            }
        }
    }
}
