CommunicationObject.OnClose Method

.NET Framework 4.5

Inserts processing on a communication object after it transitions to the closing state due to the invocation of a synchronous close operation.

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

Syntax

C++

protected abstract void OnClose(
	TimeSpan timeout
)

Parameters

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

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.
CommunicationException	A communication error occurred while closing the object.

Remarks

The Close method calls OnClose if the communication object is initially in the Opened state.

To insert processing after a communication object transitions to a closing state due to the invocation of an asynchronous BeginClose operation, use the OnBeginClose method.
