Microsoft Silverlight will reach end of support after October 2021. Learn more.

Creates a new UdpSingleSourceMulticastClient UDP client that can subscribe to a group address and receive datagrams from a single source.

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

Syntax

'Declaration
Public Sub New ( _
    sourceAddress As IPAddress, _
    groupAddress As IPAddress, _
    localPort As Integer _
)

public UdpSingleSourceMulticastClient(
    IPAddress sourceAddress,
    IPAddress groupAddress,
    int localPort
)

Parameters

  • sourceAddress
    Type: System.Net.IPAddress
    The sender source address for this receiver to subscribe to.
  • groupAddress
    Type: System.Net.IPAddress
    The multicast group address for this receiver to subscribe to.
  • localPort
    Type: System.Int32
    The local port for this receiver to bind to.

Exceptions

Exception Condition
ArgumentException

sourceAddress and groupAddress must be the same address family.
ArgumentNullException

sourceAddress is nulla null reference (Nothing in Visual Basic).

-or-

groupAddress is nulla null reference (Nothing in Visual Basic).
ArgumentOutOfRangeException

localPort is less than 0

-or-

localPort is greater than 65,535.
SocketException

Remarks

The UdpSingleSourceMulticastClient constructor associates a UDP multicast socket with a group address and port, but does not bind or otherwise use the socket.

The groupAddress parameter may be either an IPv6 or IPv4 multicast address. However, the address family of the sourceAddress and groupAddress parameters must the same.

The localPort parameter must not specify a port less than 1,024.
