CommunicationObject.OnOpen Method

When implemented in a derived class, 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)

Syntax

'Declaration
Protected MustOverride Sub OnOpen ( _
    timeout As TimeSpan _
)
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.

Exceptions

Exception Condition
ArgumentOutOfRangeException

timeout is less than zero.

TimeoutException

The interval of time specified by timeout that was allotted for the operation was exceeded before the operation was completed.

Remarks

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.
