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.

Exception Condition
InvalidOperationException

The communication object is not in a Opened or Opening state and cannot be modified.

ObjectDisposedException

The communication object is in a Closing or Closed state and cannot be modified.

CommunicationObjectFaultedException

The communication object is in a Faulted state and cannot be modified.

TimeoutException

The default interval of time that was allotted for the operation was exceeded before the operation was completed.

The BeginClose method calls OnBeginClose 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 a synchronous Close operation, use the OnClose(TimeSpan)method.
