Begins an asynchronous operation to transmit a request message to the reply side of a request-reply message exchange.
Overloads
BeginRequest(Message, AsyncCallback, Object) |
Begins an asynchronous operation to transmit a request message to the reply side of a request-reply message exchange. |

Begins an asynchronous operation to transmit a request message to the reply side of a request-reply message exchange.
public:
IAsyncResult ^ BeginRequest(System::ServiceModel::Channels::Message ^ message, AsyncCallback ^ callback, System::Object ^ state);
public IAsyncResult BeginRequest (System.ServiceModel.Channels.Message message, AsyncCallback callback, object state);
abstract member BeginRequest : System.ServiceModel.Channels.Message * AsyncCallback * obj -> IAsyncResult
Public Function BeginRequest (message As Message, callback As AsyncCallback, state As Object) As IAsyncResult
Parameters
- callback
- AsyncCallback
The AsyncCallback delegate that receives the notification of the completion of the asynchronous operation transmitting a request message.
- state
- Object
An object, specified by the application, that contains state information associated with the asynchronous operation transmitting a request message.
Returns
The IAsyncResult that references the asynchronous message transmission.
Examples
The following code shows how to implement this method.
public IAsyncResult BeginRequest(Message message,
AsyncCallback callback, object state)
{
return this.InnerChannel.BeginRequest(message,
callback, state);
}
Remarks
If the request message is larger that the maximum message size allowed by the binding being used, a QuotaExceededException is thrown. The maximum message size is set by the MaxReceivedMessageSize property. The default value is 65536 bytes.

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.
public:
IAsyncResult ^ BeginRequest(System::ServiceModel::Channels::Message ^ message, TimeSpan timeout, AsyncCallback ^ callback, System::Object ^ state);
public IAsyncResult BeginRequest (System.ServiceModel.Channels.Message message, TimeSpan timeout, AsyncCallback callback, object state);
abstract member BeginRequest : System.ServiceModel.Channels.Message * TimeSpan * AsyncCallback * obj -> IAsyncResult
Public Function BeginRequest (message As Message, timeout As TimeSpan, callback As AsyncCallback, state As Object) As IAsyncResult
Parameters
- timeout
- TimeSpan
The TimeSpan that specifies the interval of time within which a response must be received.
- callback
- AsyncCallback
The AsyncCallback delegate that receives the notification of the completion of the asynchronous operation transmitting a request message.
- state
- Object
An object, specified by the application, that contains state information associated with the asynchronous operation transmitting a request message.
Returns
The IAsyncResult that references the asynchronous message transmission.
Examples
The following code shows how to implement this method:
public IAsyncResult BeginRequest(Message message,
TimeSpan timeout, AsyncCallback callback,
object state)
{
return this.InnerChannel.BeginRequest(message,
timeout, callback, state);
}
Remarks
If the request message is larger that the maximum message size allowed by the binding being used, a QuotaExceededException should be thrown. The maximum message size is set by the MaxReceivedMessageSize property. The default value is 65536 bytes.
If a timeout
is passed while calling the function then that value is used. If the SendTimeout is set on the binding, then the value on the binding is used if no timeout
is specified while calling the function.
The DefaultSendTimeout is used if no timeout is specified on either the binding or while calling the function. This default value is 1 minute.
Notes to Implementers
The operation should throw a TimeoutException if the specified timeout
is exceeded before the operation is completed.
