Der ForEachSchemaRowsetEnumerator-Typ macht folgende Elemente verfügbar.

Konstruktoren

	Name	Beschreibung
	ForEachSchemaRowsetEnumerator	Initializes a new instance of the ForEachSchemaRowsetEnumerator class.

Zum Anfang

Eigenschaften

	Name	Beschreibung
	CollectionEnumerator	Gets or sets Boolean that indicates if the foreach loop enumerator is enumerating collections of objects or enumerating collections of collections. (Geerbt von ForEachEnumerator.)
	Connection	Gets or sets a String that contains the connection information for the schema rowset enumerator.
	ForEachEnumeratorDescription	Returns a description for the ForEachSchemaRowsetEnumerator.
	ForEachEnumeratorDisplayName	Gets or sets a String that contains the display name for the enumerator.
	Restrictions	Gets or sets an array of Strings that contains the restrictions to apply to the rowset that is returned.
	SchemaRowset	Gets or sets the GUID of the schema
	Version	Returns the version number of the package. This property is read-only. (Geerbt von ForEachEnumerator.)

Methoden

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