[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Begins an asynchronous operation to open a communication object.
Namespace: System.ServiceModel
Assembly: System.ServiceModel (in System.ServiceModel.dll)
Syntax
Private Function BeginOpen ( _
callback As AsyncCallback, _
state As Object _
) As IAsyncResult Implements ICommunicationObject.BeginOpen
IAsyncResult ICommunicationObject.BeginOpen(
AsyncCallback callback,
Object state
)
Parameters
- callback
Type: System..::.AsyncCallback
The AsyncCallback delegate that receives notification of the completion of the asynchronous open operation.
- state
Type: System..::.Object
An object, specified by the application, that contains state information associated with the asynchronous open operation.
Return Value
Type: System..::.IAsyncResult
The IAsyncResult that references the asynchronous open operation.
Implements
ICommunicationObject..::.BeginOpen(AsyncCallback, Object)
Remarks
When an ICommunicationObject is instantiated, it begins in the Created state. In the Created state, the object can be configured (for example, properties can be set, or events can be registered), but it is not yet usable to send or receive messages. The BeginOpen method causes an ICommunicationObject to enter into the Opening state, where it remains until the open operation succeeds, the open operation times out or fails and the object becomes faulted, or the ICommunicationObject is aborted.
