ICommunicationObject.BeginClose Method (TimeSpan, AsyncCallback, Object)

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

Begins an asynchronous operation to close a communication object with a specified time-out.

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

Syntax

'Declaration
Function BeginClose ( _
    timeout As TimeSpan, _
    callback As AsyncCallback, _
    state As Object _
) As IAsyncResult

IAsyncResult BeginClose(
    TimeSpan timeout,
    AsyncCallback callback,
    Object state
)

Parameters

  • timeout
    Type: System.TimeSpan
    The Timespan that specifies how long the send operation has to complete before timing out.
  • state
    Type: System.Object
    An object, specified by the application, that contains state information associated with the asynchronous close operation.

Return Value

Type: System.IAsyncResult
The IAsyncResult that references the asynchronous close operation.

Exceptions

Exception Condition
CommunicationObjectFaultedException

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

The specified time-out elapsed before the ICommunicationObject was able to close gracefully.

Remarks

This method causes an ICommunicationObject to gracefully transition from any state, other than the Opened state to the Closed state within a specified interval of time. The BeginClose() method allows any unfinished work to be completed before returning. (For example, finish sending any buffered messages.)
