   IPGlobalProperties ^ properties = IPGlobalProperties::GetIPGlobalProperties();
   IcmpV6Statistics ^ statistics = properties->GetIcmpV6Statistics();

      statistics->MembershipReductionsSent, statistics->MembershipReductionsReceived );
   Console::WriteLine( "  Reports .............................. Sent: {0,-10}   Received: {1,-10}", 
      statistics->MembershipReportsSent, statistics->MembershipReportsReceived );
}

    Console.WriteLine ("  Reports .............................. Sent: {0,-10}   Received: {1,-10}",
    statistics.MembershipReportsSent, statistics.MembershipReportsReceived);
}

Public Shared Sub ShowIcmpV6MembershipData() 
    Dim properties As IPGlobalProperties = IPGlobalProperties.GetIPGlobalProperties()
    Dim statistics As IcmpV6Statistics = properties.GetIcmpV6Statistics()
    Console.WriteLine("  Queries .............................. Sent: {0,-10}   Received: {1,-10}", statistics.MembershipQueriesSent, statistics.MembershipQueriesReceived)

Remarks

Multicast routers send Group Membership Query messages to learn which groups have members on each of their attached physical networks. Host computers respond to a Group Membership Query message by sending a Group Membership Report for each multicast group joined by the host. A host computer can also send a Group Membership Report when it joins a new multicast group. Group Membership Reduction messages are sent when a host computer leaves a multicast group.
