Элементы TaskHost

Provides a container that encapsulates a single task. In the SSIS Designer, the TaskHost is not configured separately; instead, it is configured when you set the properties of the task it encapsulates.

Тип TaskHost предоставляет доступ к следующим элементам.

Методы

	Имя	Описание
	AcceptBreakpointManager	This method is called by the run-time engine when a task or container is created, and passes it a BreakpointManager manager to allow the task to create, remove, and check the status of breakpoints. This method is called by the runtime and is not used in code. (Наследуется из DtsContainer.)
	Dispose	Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources. (Наследуется из DtsContainer.)
	Equals	Determines whether two object instances are equal. (Наследуется из DtsObject.)
	Execute	Runs the application, container, or package as part of a package workflow. (Наследуется из DtsContainer.)
	Finalize	(Наследуется из Object.)
	GetExpression	Returns the expression for the specified property. Null means no expression is assigned.
	GetHashCode	Returns the hash code for this instance. (Наследуется из DtsObject.)
	GetPackagePath	Returns the path to the task location.
	GetType	(Наследуется из Object.)
	LoadFromXML	This method is not callable by your application code. To load a package saved as .xml, use the Application..::..LoadPackage method. (Наследуется из DtsContainer.)
	MemberwiseClone	(Наследуется из Object.)
	ResumeExecution	Resumes execution of the task after pausing. The task or container is resumed by the runtime engine. (Наследуется из DtsContainer.)
	SaveToXML	This method is not callable by your application code. To save a package as .xml, use the Application..::..SaveToXml method. (Наследуется из DtsContainer.)
	SetExpression	Assigns the specified expression to the property. Specify nullNothingnullptrunitпустая ссылка (Nothing в Visual Basic) to remove an existing expression from the property.
	SetWrappedExecutable	Инфраструктура. (Наследуется из EventsProvider.)
	SuspendExecution	Called when the executable needs to suspend. This method is called by the runtime engine. (Наследуется из DtsContainer.)
	ToString	(Наследуется из Object.)
	Validate	Allows the container to determine if it contains invalid settings that will prevent it from executing successfully. (Наследуется из DtsContainer.)
