Properties

	Name	Description
	DefaultCloseTimeout	When overridden in a derived class, gets the default interval of time provided for a close operation to complete. (Inherited from CommunicationObject.)
	DefaultOpenTimeout	When overridden in a derived class, gets the default interval of time provided for an open operation to complete. (Inherited from CommunicationObject.)
	DefaultReceiveTimeout	When overridden in a derived class, gets the default interval of time a channel has to complete the reception of a message.
	DefaultSendTimeout	When overridden in a derived class, gets the default interval of time a channel has to complete the sending of a message.
	IsDisposed	Gets a value that indicates whether the communication object has been disposed. (Inherited from CommunicationObject.)
	State	Gets a value that indicates the current state of the communication object. (Inherited from CommunicationObject.)
	ThisLock	Gets the mutually exclusive lock that protects the class instance during a state transition. (Inherited from CommunicationObject.)

	BeginClose(TimeSpan, AsyncCallback, Object)	Begins an asynchronous operation to close a communication object with a specified timeout. (Inherited from CommunicationObject.)
	BeginOpen(AsyncCallback, Object)	Begins an asynchronous operation to close a communication object. (Inherited from CommunicationObject.)
	BeginOpen(TimeSpan, AsyncCallback, Object)	Begins an asynchronous operation to close a communication object within a specified interval of time. (Inherited from CommunicationObject.)
	Close()	Causes a communication object to transition from its current state into the closed state. (Inherited from CommunicationObject.)
	Close(TimeSpan)	Causes a communication object to transition from its current state into the closed state within a specified interval of time. (Inherited from CommunicationObject.)
	EndClose	Completes an asynchronous operation to close a communication object. (Inherited from CommunicationObject.)

Remarks

Specifically, this class provides a common base implementation for the ChannelFactoryBase and ChannelListenerBase channel manager classes for managing the default timeouts that are associated with the channel factories and listeners. Channels are added to the list maintained by the manager by using one of the CreateChannel methods. Abstract properties for send and receive timeouts used by the channels and listeners that are produced are specified to coordinate the values set for the derived channel and listener factories.

The ChannelBase, which provides the base implementation for custom channels, gets its default communication timeouts for the open, close, send and receive operations from the ChannelManagerBase associated with it.

The ChannelBase also takes care of managing the manager for you. In addition to exposing a reference to the manager, the base class also notifies the manager when channels are created and destroyed. But the reference to the manager is only good until the channel is destroyed.
