IChannel Interface
Definition
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Defines the basic interface that all channel objects must implement. It requires that they implement the state machine interface shared by all communication objects and that they implement a method to retrieve objects from the channel stack.

Remarks
Important
Calling methods from classes that implement this interface with untrusted data is a security risk. Call the methods from classes that implement this interface only with trusted data. For more information, see Validate All Inputs.
Channels must satisfy the contract of a state machine as defined by the ICommunicationObject interface.
The IChannel interface adds the
GetProperty method to the ICommunicationObject interface. This method provides a mechanism for retrieving properties from the channel stack regardless of where in the stack those properties live. The term "property" in the method name refers to a piece of information that belongs to one of the channels in the stack. The CLR type for that property is determined by T
. This method of retrieval is also used on channel factories and channel listeners.
IChannel
is inherited by each of the channel interfaces associated with the basic message-exchange patterns:
IInputChannel for receiving messages.
IOutputChannel for sending messages.
IRequestChannel for sending a request.
IReplyChannel for sending a reply.
IDuplexChannel for bi-directional messaging.
Properties
State |
Gets the current state of the communication-oriented object. (Inherited from ICommunicationObject) |
Methods
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 timeout. (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(IAsyncResult) |
Completes an asynchronous operation to close a communication object. (Inherited from ICommunicationObject) |
EndOpen(IAsyncResult) |
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. |
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
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) |
