[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Begins an asynchronous operation to transmit a message to the destination of the output channel within a specified interval of time.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
'Declaration Function BeginSend ( _ message As Message, _ timeout As TimeSpan, _ callback As AsyncCallback, _ state As Object _ ) As IAsyncResult
Parameters
- message
- Type: System.ServiceModel.Channels.Message
The Message being sent on the output channel.
- timeout
- Type: System.TimeSpan
The TimeSpan that specifies how long the send operation has to complete before timing out.
- callback
- Type: System.AsyncCallback
The AsyncCallback delegate that receives the notification of the asynchronous operation send completion.
- state
- Type: System.Object
An object, specified by the application, that contains state information associated with the asynchronous send operation.
Return Value
Type: System.IAsyncResultThe IAsyncResult that references the asynchronous send operation.
The destination for messages sent on an output channel is specified at channel creation time.
The BeginSend(Message, TimeSpan, AsyncCallback, Object) method does not guarantee the delivery of message to the remote endpoint. If delivery guarantees are required, use IOutputSessionChannel.
If the message sent 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.
Notes to ImplementersThe operation should throw a TimeoutException if the specified timeout is exceeded.
