IRequestChannel Interface
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Defines the contract that a channel must implement to be on the requesting side of a request-reply communication between messaging endpoints.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
The IRequestChannel type exposes the following members.
| Name | Description | |
|---|---|---|
 | RemoteAddress | Gets the remote address to which the request channel sends messages. |
| State | Gets the current state of the communication-oriented object. (Inherited from ICommunicationObject.) |
| Via | Gets the transport address to which the request is send. |
| 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.) |
| BeginRequest(Message, AsyncCallback, Object) | Begins an asynchronous operation to transmit a request message to the reply-side of a request-reply message exchange. |
| BeginRequest(Message, TimeSpan, AsyncCallback, Object) | Begins an asynchronous operation to transmit a request message to the reply-side of a request-reply message exchange within a specified interval of time. |
| 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.) |
| EndRequest | Completes an asynchronous operation to return a message-based response to a transmitted request. |
| 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.) |
| Request(Message) | Sends a message-based request and returns the correlated message-based response. |
| Request(Message, TimeSpan) | Sends a message-based request and returns the correlated message-based response within a specified interval of time. |
| 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.) |
The IRequestChannel defines synchronous and asynchronous variants of an Request(Message) method that returns a response message. It also provides a RemoteAddress and Via properties to retrieve the endpoint address and URI to which the request message is sent.
