PingCompletedEventArgs.Reply Property

Gets an object that contains data that describes an attempt to send an Internet Control Message Protocol (ICMP) echo request message and receive a corresponding ICMP echo reply message.

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

public PingReply Reply { get; }

Property Value

Type: System.Net.NetworkInformation.PingReply
A PingReply object that describes the results of the ICMP echo request.

If the value of Status is not Success, you should not use the values that are returned by the RoundTripTime, Options, and Buffer properties. The RoundTripTime and Buffer properties will return zero, and the Options property will return null.

The following code example implements a method that is used to respond to a PingCompleted event. For the complete example, see the PingCompletedEventArgs class overview.

private static void PingCompletedCallback (object sender, PingCompletedEventArgs e)
{
    // If the operation was canceled, display a message to the user. 
    if (e.Cancelled)
    {
        Console.WriteLine ("Ping canceled.");

        // Let the main thread resume.  
        // UserToken is the AutoResetEvent object that the main thread  
        // is waiting for.
        ((AutoResetEvent)e.UserState).Set ();
    }

    // If an error occurred, display the exception to the user. 
    if (e.Error != null)
    {
        Console.WriteLine ("Ping failed:");
        Console.WriteLine (e.Error.ToString ());

        // Let the main thread resume. 
        ((AutoResetEvent)e.UserState).Set();
    }

    PingReply reply = e.Reply;

    DisplayReply (reply);

    // Let the main thread resume.
    ((AutoResetEvent)e.UserState).Set();
}
void PingCompletedCallback (Object* /*sender*/, PingCompletedEventArgs* e)
{
    // If the operation was canceled, display a message to the user.
    if (e->Cancelled)
    {
        Console::WriteLine (S"Ping canceled.");

        // Let the main thread resume. 
        // UserToken is the AutoResetEvent object that the main thread 
        // is waiting for.
        (dynamic_cast<AutoResetEvent*>(e->UserToken))->Set ();
    }

    // If an error occurred, display the exception to the user.
    if (e->Error != 0)
    {
        Console::WriteLine (S"Ping failed:");
        Console::WriteLine (e->Error->ToString ());

        // Let the main thread resume. 
        (dynamic_cast<AutoResetEvent*>(e->UserToken))->Set ();
    }

    PingReply* reply = e->Reply;

    DisplayReply (reply);

    // Let the main thread resume.
    (dynamic_cast<AutoResetEvent*>(e->UserToken))->Set ();
}
