Defines the interface for the context control of a channel.

Namespace: System.ServiceModel
Assembly: System.ServiceModel (in System.ServiceModel.dll)

Syntax

'Declaration
Public Interface IContextChannel _
    Inherits IChannel, ICommunicationObject, IExtensibleObject(Of IContextChannel)

public interface IContextChannel : IChannel, 
    ICommunicationObject, IExtensibleObject<IContextChannel>

The IContextChannel type exposes the following members.

Properties

	Name	Description
	AllowOutputBatching	Gets or sets a value that instructs Silverlight 5 to store a set of messages before giving the messages to the transport.
	Extensions	Gets a collection of extension objects for this extensible object. (Inherited from IExtensibleObject<T>.)
	InputSession	Gets the input session for the channel.
	LocalAddress	Gets the local endpoint for the channel.
	OperationTimeout	Gets or sets the time period within which an operation must complete or an exception is thrown.
	OutputSession	Gets the output session associated with the channel, if any.
	RemoteAddress	Gets the remote address associated with the channel.
	SessionId	Returns an identifier for the current session, if any.
	State	Gets the current state of the communication-oriented object. (Inherited from ICommunicationObject.)

Methods

	Name	Description
	Abort	Causes a communication object to transition immediately from its current state into the closed state. (Inherited from ICommunicationObject.)
	BeginClose(AsyncCallback, Object)	Begins an asynchronous operation to close a communication object. (Inherited from ICommunicationObject.)
	BeginClose(TimeSpan, AsyncCallback, Object)	Begins an asynchronous operation to close a communication object with a specified time-out. (Inherited from ICommunicationObject.)
	BeginOpen(AsyncCallback, Object)	Begins an asynchronous operation to open a communication object. (Inherited from ICommunicationObject.)
	BeginOpen(TimeSpan, AsyncCallback, Object)	Begins an asynchronous operation to open a communication object within a specified interval of time. (Inherited from ICommunicationObject.)
	Close()	Causes a communication object to transition from its current state into the closed state. (Inherited from ICommunicationObject.)
	Close(TimeSpan)	Causes a communication object to transition from its current state into the closed state. (Inherited from ICommunicationObject.)
	EndClose	Completes an asynchronous operation to close a communication object. (Inherited from ICommunicationObject.)
	EndOpen	Completes an asynchronous operation to open a communication object. (Inherited from ICommunicationObject.)
	GetProperty<T>	Returns a typed object requested, if present, from the appropriate layer in the channel stack. (Inherited from IChannel.)
	Open()	Causes a communication object to transition from the created state into the opened state. (Inherited from ICommunicationObject.)
	Open(TimeSpan)	Causes a communication object to transition from the created state into the opened state within a specified interval of time. (Inherited from ICommunicationObject.)

Events

	Name	Description
	Closed	Occurs when the communication object completes its transition from the closing state into the closed state. (Inherited from ICommunicationObject.)
	Closing	Occurs when the communication object first enters the closing state. (Inherited from ICommunicationObject.)
	Faulted	Occurs when the communication object first enters the faulted state. (Inherited from ICommunicationObject.)
	Opened	Occurs when the communication object completes its transition from the opening state into the opened state. (Inherited from ICommunicationObject.)
	Opening	Occurs when the communication object first enters the opening state. (Inherited from ICommunicationObject.)

Remarks

The IContextChannel defines the controls for the context of a channel. This includes the SessionId, InputSession, OutputSession, and AllowOutputBatching for the channel, and the LocalAddress and RemoteAddress for the endpoints that are participating in the session. The IContextChannel interface forms part of the IServiceChannel and IClientChannel interfaces and of the IDuplexContextChannel interface.
