IcmpV4Statistics.DestinationUnreachableMessagesReceived Property

public:
 abstract property long DestinationUnreachableMessagesReceived { long get(); };

public abstract long DestinationUnreachableMessagesReceived { get; }

member this.DestinationUnreachableMessagesReceived : int64

Public MustOverride ReadOnly Property DestinationUnreachableMessagesReceived As Long

An Int64 value that specifies the total number of Destination Unreachable messages that were received.

The following example displays the value of this property.

public static void ShowIcmpV4UnreachableData()
{
    IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
    IcmpV4Statistics statistics = properties.GetIcmpV4Statistics();
    Console.WriteLine("  Destination Unreachables ............ Sent: {0,-10}   Received: {1,-10}",
        statistics.DestinationUnreachableMessagesSent,
        statistics.DestinationUnreachableMessagesReceived);
}

Public Shared Sub ShowIcmpV4UnreachableData() 
    Dim properties As IPGlobalProperties = IPGlobalProperties.GetIPGlobalProperties()
    Dim statistics As IcmpV4Statistics = properties.GetIcmpV4Statistics()
    Console.WriteLine("  Destination Unreachables ............ Sent: {0,-10}   Received: {1,-10}", statistics.DestinationUnreachableMessagesSent, statistics.DestinationUnreachableMessagesReceived)

End Sub

A Destination Unreachable message can be sent to the computer that is the source of a packet for any of the following reasons:

• The computer cannot find a route to the destination address.

• Communication with the destination address is administratively prohibited. For example, a firewall prevents delivery of packets to the destination.

• The destination address is unreachable.

• The destination port is unreachable. For example, there is no listener available for the packet's protocol.
