Causes a communication object to transition from its current state into the closed state.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
This method causes an ICommunicationObject to gracefully transition from the Opened state to the Closed state. The Close method allows any unfinished work to be completed before returning. For example, finish sending any buffered messages).
If Close is called on an ICommunicationObject in the Created, Opening, or Faulted state, the ICommunicationObject is aborted. If Close is called on an ICommunicationObject in the Closing or Closed state, the call returns immediately.
There is also an asynchronous version of the close method that is initiated by calling BeginClose and completed by calling Close.
