Assembly: System (in system.dll)

public function get Options () : PingOptions

Not applicable.

Property Value

A PingOptions object that contains the Time to Live (TTL) and the fragmentation directive used for transmitting the reply if Status is Success; otherwise, a null reference (Nothing in Visual Basic).

The TTL defines the number of times nodes can forward a packet as it travels between its source and destination. If the number of forwards, also known as hops, exceeds the value specified for the TTL, the packet is deemed undeliverable and is discarded.

The DontFragment value specified in the ICMP echo request controls packet fragmentation. If DontFragment is true and the packet size exceeds the maximum transmission unit of the network path taken by the packet, the packet is discarded and the PacketTooBig error is returned.

The following code example sends an ICMP echo request synchronously and displays the values stored in the PingOptions object returned by this property.

public static void LocalPing ()
{
    // Ping's the local machine.
    Ping pingSender = new Ping ();
    IPAddress address = IPAddress.Loopback;
    PingReply reply = pingSender.Send (address);

    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);
    }
    else
    {
        Console.WriteLine (reply.Status);
    }
}
