ForEachEnumerator 型別公開下列成員。

建構函式

	名稱	說明
	ForEachEnumerator	Initializes a new instance of the ForEachEnumerator class.

上層

屬性

	名稱	說明
	CollectionEnumerator	Gets or sets Boolean that indicates if the foreach loop enumerator is enumerating collections of objects or enumerating collections of collections.
	Version	Returns the version number of the package. This property is read-only.

方法

	名稱	說明
	CanUpdate	A Boolean that indicates if the new package XML can update the old package XML.
	Equals	Determines whether two object instances are equal. (繼承自 DtsObject。)
	Finalize	(繼承自 Object。)
	GetEnumerator	Returns a managed enumerator, IEnumerator, for iterating over the collections.
	GetHashCode	Returns the hash code for this instance. (繼承自 DtsObject。)
	GetType	(繼承自 Object。)
	InitializeForEachEnumerator	Initializes the properties associated with the task. This method is called by the runtime and is not used in code.
	MemberwiseClone	(繼承自 Object。)
	ToString	(繼承自 Object。)
	Update	This method updates the old package XML with the new package XML if CanUpdate is set to true.
	Validate	Allows the container to determine if it contains invalid settings that will prevent it from executing successfully.

備註

This class provides the abstract (MustInherit in Visual Basic) base class for enumerators over the foreach loop collection. Inherits from DtsObject and IDTSForEachEnumerator.
