CommunicationObject.OnOpen Method

Inserts processing on a communication object after it transitions into the opening state which must complete within a specified interval of time.

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

protected abstract void OnOpen(
	TimeSpan timeout
)

Parameters

timeout
Type: System.TimeSpan

The Timespan that specifies how long the on open operation has to complete before timing out.

ExceptionCondition
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 Open method calls OnOpen(TimeSpan) (after calling OnOpening and before calling OnOpened) if the communication object is initially in the Created state.

To insert processing as a communication object transitions to a opening state due to the invocation of an asynchronous OnBeginOpen(TimeSpan, AsyncCallback, Object) operation, use the OnOpening method.
