PingReply.Status Eigenschap

public:
 property System::Net::NetworkInformation::IPStatus Status { System::Net::NetworkInformation::IPStatus get(); };

public System.Net.NetworkInformation.IPStatus Status { get; }

member this.Status : System.Net.NetworkInformation.IPStatus

Public ReadOnly Property Status As IPStatus

Waarde van eigenschap

Een IPStatus waarde die het resultaat van de aanvraag aangeeft.

Voorbeelden

In het volgende codevoorbeeld ziet u hoe u Ping een ICMP-echoaanvraag synchroon verzendt en het antwoord weergeeft.

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);
            }
        }
    }
}

        0
    | _ ->
        eprintfn "Error sending ping: %O" reply
        eprintfn "Error was: %O" reply.Status
        1

Opmerkingen

Als de waarde Status niet Successis, moet u de waarden die worden geretourneerd door de RoundtripTimeof OptionsBuffer eigenschappen niet gebruiken. De RoundtripTime en Buffer eigenschappen retourneren nul en de Options eigenschap wordt geretourneerd null.
