IcmpV6Statistics.MembershipReductionsSent Property

Gets the number of Internet Group Management Protocol (IGMP) Group Membership Reduction messages sent.

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

public abstract long MembershipReductionsSent { get; }

Property Value

Type: System.Int64
An Int64 value that specifies the total number of Group Membership Reduction messages sent.

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.

The following example displays the value of this property.

public static void ShowIcmpV6MembershipData ()
{
    IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
    IcmpV6Statistics statistics = properties.GetIcmpV6Statistics();
    Console.WriteLine ("  Queries .............................. Sent: {0,-10}   Received: {1,-10}", 
    statistics.MembershipQueriesSent, statistics.MembershipQueriesReceived);
    Console.WriteLine ("  Reductions ........................... Sent: {0,-10}   Received: {1,-10}", 
    statistics.MembershipReductionsSent, statistics.MembershipReductionsReceived);
    Console.WriteLine ("  Reports .............................. Sent: {0,-10}   Received: {1,-10}", 
    statistics.MembershipReportsSent, statistics.MembershipReportsReceived);
}
void ShowIcmpV6MembershipData ()
{
    IPGlobalProperties* properties = IPGlobalProperties::GetIPGlobalProperties();
    IcmpV6Statistics* statistics = properties->GetIcmpV6Statistics();
    Console::WriteLine (S"  Queries .............................. Sent: {0,-10}   Received: {1,-10}",
        __box(statistics->MembershipQueriesSent), __box(statistics->MembershipQueriesReceived));
    Console::WriteLine (S"  Reductions ........................... Sent: {0,-10}   Received: {1,-10}",
        __box(statistics->MembershipReductionsSent), __box(statistics->MembershipReductionsReceived));
    Console::WriteLine (S"  Reports .............................. Sent: {0,-10}   Received: {1,-10}",
        __box(statistics->MembershipReportsSent), __box(statistics->MembershipReportsReceived));
}
