CommunicationObject.BeginClose Method (AsyncCallback, Object)
Begins an asynchronous operation to close a communication object.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
- Type: System.AsyncCallback
The AsyncCallback delegate that receives notification of the completion of the asynchronous close operation.
- Type: System.Object
An object, specified by the application, that contains state information associated with the asynchronous close operation.
Return ValueType: System.IAsyncResult
The IAsyncResult that references the asynchronous close operation.
This method causes the CommunicationObject to gracefully transition from any state, other than the Closed state, into the Closed state within a default interval of time. The BeginClose method allows any unfinished work to be completed before returning. For example, finish sending any buffered messages). This method calls OnBeginOpen(TimeSpan, AsyncCallback, Object) if the communication object was initially in the Opened state.
