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.) |
