Konstruktoren

	Name	Beschreibung
	ForEachEnumeratorHostClass	Infrastruktur Initializes a new instance of the ForEachEnumeratorHostClass class.

Zum Anfang

Eigenschaften

	Name	Beschreibung
	CollectionEnumerator	Infrastruktur Gets or sets a Boolean that indicates if the hosting enumerator is enumerating collections of objects or enumerating collections of collections.
	CreationName	Infrastruktur Returns the string that is used by the run-time to create an instance of the ForEachItemEnumeratorClass object. This property is read-only.
	DelayValidation	Infrastruktur Gets or sets a Boolean that indicates whether ForEachItemEnumeratorClass validation is delayed until the package runs.
	Description	Infrastruktur Gets or sets description for the host.
	HostType	Infrastruktur Gets an enumeration that describes the type of host that the ForEachItemEnumeratorClass is being used by. This property is read-only.
	ID	Infrastruktur Returns the GUID assigned to the host.
	InnerObject	Infrastruktur Returns the inner object of the host, which is the ForEachItemEnumeratorClass that is being hosted.
	Name	Infrastruktur Gets or sets a name for the host.
	Properties	Infrastruktur Returns a IDTSProperties100 collection that contains IDTSProperty100 objects. Each IDTSProperty100 has additional information about each task in the ForEachItemEnumeratorClass.

Methoden

	Name	Beschreibung
	ComputeExpressions	Infrastruktur Computes the expressions in the property collection.
	Equals	(Geerbt von Object.)
	Finalize	(Geerbt von Object.)
	GetEnumerator	Infrastruktur Returns an IEnumerator interface for use in iterating over the ForEachItemEnumeratorClass.
	GetExpression	Infrastruktur Returns a String that contains the expression for the specified property. Null means no expression is assigned.
	GetHashCode	(Geerbt von Object.)
	GetType	(Geerbt von Object.)
	InitializeForEachEnumerator	Infrastruktur Initializes the properties associated with the task.
	MemberwiseClone	(Geerbt von Object.)
	SetExpression	Infrastruktur Assigns the specified expression to the property. Specify nullein NULL-Verweis (Nothing in Visual Basic) to remove an existing expression from the property.
	ToString	(Geerbt von Object.)
	Validate	Infrastruktur Allows the host to determine if there are invalid settings that will prevent the ForEachItemEnumeratorClass from executing successfully.
