Causes a communication object to transition from its current state into the closed state within a specified interval of time.

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

Syntax

'Declaration
Public Sub Close ( _
    timeout As TimeSpan _
)

public void Close(
    TimeSpan timeout
)

Parameters

  • timeout
    Type: System.TimeSpan
    The Timespan that specifies how long the close operation has to complete before timing out.

ICommunicationObject.Close(TimeSpan)

Exceptions

Close was called on an object in the Faulted state.

TimeoutException

Remarks

This method causes a CommunicationObject to gracefully transition from any state, other than the Closed state, into the Closed state within a specified interval of time. 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.
