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

Causes a communication object to transition from its current state into the closed state.

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

Syntax

'Declaration
Public Sub Close

public void Close()

Implements

ICommunicationObject.Close()

Exceptions

Exception Condition
CommunicationObjectFaultedException

Close 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 a CommunicationObject to gracefully transition from any state, other than the Closed state, into the Closed state. The Close method allows any unfinished work to be completed before returning. For example, finish sending any buffered messages.

The CommunicationObject enters the Closing state and remains in it after the Close method is called until the transition to the Closed state is completed. The transition consists of making successive calls to OnClosing, OnClose(TimeSpan), and OnClosed.

There is also an asynchronous version of the close method that is initiated by calling BeginClose.
