Syntax

'Declaration
Public Function BeginClose ( _

    state As Object _
) As IAsyncResult

public IAsyncResult BeginClose(

    Object state
)

Parameters

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

ICommunicationObject.BeginClose(AsyncCallback, Object)

Exceptions

Exception Condition
CommunicationObjectFaultedException

BeginClose was called on an object in the Faulted state.
TimeoutException

The default interval of time that was allotted for the operation was exceeded before the operation was completed.

Remarks

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.
