IPv6MulticastOption.InterfaceIndex Property

Definition

Namespace:

System.Net.Sockets

Assembly:

System.Net.Sockets.dll

Source:

MulticastOption.cs

Gets or sets the interface index that is associated with a multicast group.

public:
 property long InterfaceIndex { long get(); void set(long value); };

public long InterfaceIndex { get; set; }

member this.InterfaceIndex : int64 with get, set

Public Property InterfaceIndex As Long

Property Value

Int64

A UInt64 value that specifies the address of the interface.

Exceptions

ArgumentOutOfRangeException

The value that is specified for a set operation is less than 0 or greater than 0x00000000FFFFFFFF.

Examples

The following example creates an IPv6MulticastOption object.

// Exercise the use of the IPv6MulticastOption.
Console::WriteLine( "Instantiate IPv6MulticastOption(IPAddress)" );

// Instantiate IPv6MulticastOption using one of the
// overloaded constructors.
IPv6MulticastOption^ ipv6MulticastOption = gcnew IPv6MulticastOption( m_GrpAddr );

// Store the IPAdress multicast options.
IPAddress^ group = ipv6MulticastOption->Group;
__int64 interfaceIndex = ipv6MulticastOption->InterfaceIndex;

// Display IPv6MulticastOption properties.
Console::WriteLine( "IPv6MulticastOption::Group: [ {0}]", group );
Console::WriteLine( "IPv6MulticastOption::InterfaceIndex: [ {0}]", interfaceIndex );

// Exercise the use of the IPv6MulticastOption.
Console.WriteLine("Instantiate IPv6MulticastOption(IPAddress)");

// Instantiate IPv6MulticastOption using one of the
// overloaded constructors.
IPv6MulticastOption ipv6MulticastOption = new IPv6MulticastOption(m_GrpAddr);

// Store the IPAdress multicast options.
IPAddress group =  ipv6MulticastOption.Group;
long interfaceIndex = ipv6MulticastOption.InterfaceIndex;

// Display IPv6MulticastOption properties.
Console.WriteLine("IPv6MulticastOption.Group: [" + group  + "]");
Console.WriteLine("IPv6MulticastOption.InterfaceIndex: [" + interfaceIndex + "]");

' Exercise the use of the IPv6MulticastOption.
Console.WriteLine("Instantiate IPv6MulticastOption(IPAddress)")

' Instantiate IPv6MulticastOption using one of the 
' overloaded constructors.
Dim ipv6MulticastOption As New IPv6MulticastOption(m_GrpAddr)

' Store the IPAdress multicast options.
Dim group As IPAddress = ipv6MulticastOption.Group
Dim interfaceIndex As Long = ipv6MulticastOption.InterfaceIndex

' Display IPv6MulticastOption properties.
Console.WriteLine(("IPv6MulticastOption.Group: [" + group.ToString() + "]"))
Console.WriteLine(("IPv6MulticastOption.InterfaceIndex: [" + interfaceIndex.ToString() + "]"))

Remarks

This property specifies the interface on which data is received or sent.
