abstract member CreateMessageSink : string * obj * string -> System.Runtime.Remoting.Messaging.IMessageSink
Public Function CreateMessageSink (url As String, remoteChannelData As Object, ByRef objectURI As String) As IMessageSink

Parameters

url
String

remoteChannelData
Object

The channel data object of the remote host to which the new sink will deliver messages. Can be null.

objectURI
String

When this method returns, contains a URI of the new channel message sink that delivers messages to the specified URL or channel data object. This parameter is passed uninitialized.

Returns

Remarks

The CreateMessageSink method returns a channel message sink that delivers messages to either the specified URL or the channel data object. If the uri parameter is null, the remoteChannelData parameter is used as a target for the sink. Either the url parameter or the remoteChannelData parameter can be null, but not both.
