Parameters

Exceptions
| Exception | Condition |
|---|---|
| CommunicationObjectFaultedException | BeginClose() was called on an object in the Faulted state. |
| TimeoutException | The default 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. The BeginClose() method allows any unfinished work to be completed before returning. (For example, finish sending any buffered messages.)
