IPv6InterfaceProperties.Index Property
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Gets the index of the network interface associated with an Internet Protocol version 6 (IPv6) address.
public:
abstract property int Index { int get(); };
public abstract int Index { get; }
member this.Index : int
Public MustOverride ReadOnly Property Index As Integer
An Int32 value that contains the index of the network interface for IPv6 address.
The following code example gets an IPv6InterfaceProperties object and displays its data.
void DisplayIPv6NetworkInterfaces()

properties->HostName, properties->DomainName );

while ( myEnum24->MoveNext() )
{
NetworkInterface ^ adapter = safe_cast<NetworkInterface ^>(myEnum24->Current);
// Only display informatin for interfaces that support IPv6.
if ( adapter->Supports( NetworkInterfaceComponent::IPv6 ) == false )
{
continue;
}
count++;
Console::WriteLine();
Console::WriteLine( adapter->Description );
// Underline the description.
Console::WriteLine( String::Empty->PadLeft( adapter->Description->Length, '=' ) );
IPInterfaceProperties ^ adapterProperties = adapter->GetIPProperties();
// Try to get the IPv6 interface properties.
IPv6InterfaceProperties ^ p = adapterProperties->GetIPv6Properties();

If the value of this property is zero, IPv6 is not supported by this interface.
