ClientChannel

Overview

The ClientChannel abstract class serves as a base class for implementing a custom Remoting SDK Transport Channel by providing a common base-implementation of the IClientChannel interface. Though a Transport Channel will typically descend from the ClientChannel class, this is not required, but all Transport Channels have to implement the IClientChannel interface.

AfterReceiveStream    (declared in Channel)

This event is triggered by client and server channels directly after a request or response stream has been received and before the stream gets parsed into a message. User code can assign handlers to this event to process, inspect or modify incoming messages, before they get handled by the Remoting SDK framework. The passed Stream is a MemoryStream and may be modified.

If no handlers are assigned to the AfterReceiveStream event, the message will load the data directly from the incoming medium (usually the network stream); assigning event handlers to AfterReceiveStream will induce a slight overhead as the data will first be copied into a local memory buffer for the event handler. This should not have any noticeably effect except for very large messages or on resource-limited systems such as Compact Framework Clients, but if utmost performance is important, take this note into consideration.

OnException

This event is raised if an exception occurs during the execution of a remote request through the channel. The event will be raised both for exceptions originating from the server and for exceptions during communication (such as unavailability of the server). Attach a handler to this event to do custom handling of events without having to reply on explicit try/catch blocks in the calling code.

This event will not be raised for SessionNotFoundExceptions. These will be handled separately by the OnLoginNeeded event.

This event is raised if an SessionNotFoundException occurs during the execution of a remote request through the channel. The event gives you the opportunity to perform a login on the server (for example by calling a custom Login method, and then retry the call by setting the EventArgs' LoginSuccessful property to true. This way, your client can recover from a timed-out session to automatically logging in again, without the calling code having to consider the handling of SessionNotFoundExceptions manually.
