Metodi

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

Osservazioni

At run time, the control flow in the ForLoop container is repeated within the overall package control flow. In each iteration of the loop, the ForLoop container evaluates an expression and repeats its workflow until the expression evaluates to false. For more information, see Contenitore Ciclo For.
