CommunicationObject.OnBeginClose Method

When implemented in a derived class, inserts processing after a communication object transitions to the closing state due to the invocation of an asynchronous close operation.

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

protected abstract IAsyncResult OnBeginClose(
	TimeSpan timeout,
	AsyncCallback callback,
	Object state
)

Parameters

timeout
Type: System.TimeSpan
The Timespan that specifies how long the on close operation has to complete before timing out.
callback
Type: System.AsyncCallback
The AsyncCallback delegate that receives notification of the completion of the asynchronous on close operation.
state
Type: System.Object
An object, specified by the application, that contains state information associated with the asynchronous on close operation.

Return Value

Type: System.IAsyncResult
The IAsyncResult that references the asynchronous on close operation.

ExceptionCondition
ArgumentOutOfRangeException

timeout is less than zero.

The BeginClose method calls OnBeginClose if the communication object is initially in the Opened state.

When implemented in a derived class, inserts processing after a communication object transitions to a closing state due to the invocation of a synchronous Close operation, use the OnClose(TimeSpan)method.
