Методы

  Имя Описание
Открытый метод Equals (Производный от Object.)
Защищенный метод Finalize (Производный от Object.)
Открытый метод GetHashCode (Производный от Object.)
Открытый метод GetType (Производный от Object.)
Защищенный метод MemberwiseClone (Производный от Object.)
Открытый метод OnBreakpointHit This method is called whenever a breakpoint is hit within a task.
Открытый метод OnCustomEvent This method is called by tasks to raise custom task-defined events.
Открытый метод OnError This event is raised by a task or container when an error occurs.
Открытый метод OnExecutionStatusChanged This event is raised by a task or container when its execution status changes.
Открытый метод OnInformation This event is raised anytime the task is to provide information.
Открытый метод OnPostExecute This method is called immediately after the execution logic of the task completes. This event is raised by a task or container immediately after it runs.
Открытый метод OnPostValidate This method is called immediately after the validation logic of the task completes. This event is raised by a task after the task is validated.
Открытый метод OnPreExecute This method is called when the execution logic begins. This event is raised by a task or a container immediately before it runs.
Открытый метод OnPreValidate This method is called when the validation logic of the task starts. This event is raised when the validation of the task host or container begins.
Открытый метод OnProgress This method is called anytime a task experiences measurable progress.
Открытый метод OnQueryCancel This method is called at any juncture in task processing where it is feasible to cancel execution. This event is raised by tasks and containers to determine whether they should stop running.
Открытый метод OnTaskFailed This event is raised by the task host when it fails.
Открытый метод OnVariableValueChanged This event is used by the Integration Services run-time. It is not called by tasks.

Замечания

Because firing of an event and generating the information sent with an event is potentially expensive, there is a mechanism for suppressing events when a client is not interested in that particular event. Every event firing method has a fireAgain parameter. If the value of this variable is false after the method returns, the caller should not fire this event again for the duration of the current execution.

For more information about the events provided by the Integration Services run-time, see Обработчики событий в службах Integration Services (SSIS).
