IOutputChannel.BeginSend Method (Message, AsyncCallback, Object)

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Begins an asynchronous operation to transmit a message to the destination of the output channel.

Namespace:  System.ServiceModel.Channels
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

Syntax

'Declaration
Function BeginSend ( _
    message As Message, _
    callback As AsyncCallback, _
    state As Object _
) As IAsyncResult

IAsyncResult BeginSend(
    Message message,
    AsyncCallback callback,
    Object state
)

Parameters

  • state
    Type: System.Object
    An object, specified by the application, that contains state information associated with the asynchronous send operation.

Return Value

Type: System.IAsyncResult
The IAsyncResult that references the asynchronous message transmission.

Remarks

The destination for messages sent out on an output channel is specified at channel creation time.

The BeginSend() method does not guarantee the delivery of message to the remote endpoint. If delivery guarantees are required, use the 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.
