IInputChannel Interface

Definition

Defines the interface that a channel must implement to receive a message.

public interface class IInputChannel : System::ServiceModel::Channels::IChannel
public interface IInputChannel : System.ServiceModel.Channels.IChannel
type IInputChannel = interface
    interface IChannel
    interface ICommunicationObject
Public Interface IInputChannel
Implements IChannel
Derived

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.

The IInputChannel contract includes synchronous and asynchronous variants of receive, try-to-receive and wait-for-a-message functionality.

The pull model is used typically with an IInputChannel to receive messages: you call Receive (to "pull" a message out of the channel) and then wait for a message to arrive. An alternative usage pattern is to call BeginWaitForMessage(TimeSpan, AsyncCallback, Object) or BeginWaitForMessage(TimeSpan, AsyncCallback, Object), and then call Receive(TimeSpan). This approach is common for transactional usages where you start the transaction between the calls to WaitForMessage(TimeSpan) and Receive.

An IInputChannel is not necessarily bound to a single sender. Other channels and channel interfaces can provide a correlation between particular senders and an IInputChannel, but the base contract makes no such restriction. An implementation can create a new IInputChannel for each message or reuse the same IInputChannel for multiple messages and senders.

Properties

LocalAddress

Gets the address on which the input channel receives messages.

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)
BeginReceive(AsyncCallback, Object)

Begins an asynchronous operation to receive a message that has a state object associated with it.

BeginReceive(TimeSpan, AsyncCallback, Object)

Begins an asynchronous operation to receive a message that has a specified time out and state object associated with it.

BeginTryReceive(TimeSpan, AsyncCallback, Object)

Begins an asynchronous operation to receive a message that has a specified time out and state object associated with it.

BeginWaitForMessage(TimeSpan, AsyncCallback, Object)

Begins an asynchronous wait-for-a-message-to-arrive operation that has a specified time out and state object associated with it.

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)
EndReceive(IAsyncResult)

Completes an asynchronous operation to receive a message.

EndTryReceive(IAsyncResult, Message)

Completes the specified asynchronous operation to receive a message.

EndWaitForMessage(IAsyncResult)

Completes the specified asynchronous wait-for-a-message operation.

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)
Receive()

Returns the message received, if one is available. If a message is not available, blocks for a default interval of time.

Receive(TimeSpan)

Returns the message received, if one is available. If a message is not available, blocks for a specified interval of time.

TryReceive(TimeSpan, Message)

Tries to receive a message within a specified interval of time.

WaitForMessage(TimeSpan)

Returns a value that indicates whether a message has arrived within a specified interval of time.

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)
