	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.

Métodos

	Nome	Descrição
	CanUpdate	A Boolean that indicates if the new package XML can update the old package XML. (Herdado de ForEachEnumerator.)
	Equals	Determines whether two object instances are equal. (Herdado de DtsObject.)
	Finalize	(Herdado de Object.)
	GetEnumerator	Returns an enumerator for iterating over the collection. (Substitui ForEachEnumerator. . :: . .GetEnumerator(Connections, VariableDispenser, IDTSInfoEvents, IDTSLogging).)
	GetHashCode	Returns the hash code for this instance. (Herdado de DtsObject.)
	GetType	(Herdado de Object.)
	InitializeForEachEnumerator	Initializes the properties associated with the task. This method is called by the runtime and is not used in code. (Herdado de ForEachEnumerator.)
	LoadFromXML	This method is not callable by your application code. To load a package saved as .xml, use the Application..::..LoadPackage method.
