Méthodes

	Nom	Description
	CanUpdate	A Boolean that indicates if the new package XML can update the old package XML. (hérité de ForEachEnumerator.)
	Equals	Determines whether two object instances are equal. (hérité de DtsObject.)
	Finalize	(hérité de Object.)
	GetEnumerator	Returns an enumerator that can iterate over the ForEachFromVarEnumerator instance. (remplace ForEachEnumerator. . :: . .GetEnumerator(Connections, VariableDispenser, IDTSInfoEvents, IDTSLogging).)
	GetHashCode	Returns the hash code for this instance. (hérité de DtsObject.)
	GetType	(hérité de Object.)
	InitializeForEachEnumerator	Initializes the properties associated with the task. This method is called by the runtime and is not used in code. (hérité de ForEachEnumerator.)
	LoadFromXML	This method is not callable by your application code. To load a package saved as .xml, use the Application..::..LoadPackage method.
	MemberwiseClone	(hérité de Object.)
	SaveToXML	This method is not callable by your application code. To save a package as .xml, use the Application..::..SaveToXml method.
	ToString	(hérité de Object.)
	Update	This method updates the old package XML with the new package XML if CanUpdate is set to true. (hérité de ForEachEnumerator.)
	Validate	Allows the container to determine if it contains invalid settings that will prevent it from executing successfully. (hérité de ForEachEnumerator.)
