方法

	名称	说明
	CanUpdate	A Boolean that indicates if the new package XML can update the old package XML. （从 ForEachEnumerator 继承。）
	Equals	Determines whether two object instances are equal. （从 DtsObject 继承。）
	ExportXML	Exports data to an .xml file.
	Finalize	（从 Object 继承。）
	GetEnumerator	Gets an IEnumerator interface for iterating through the ForEachItem collection. （覆盖 ForEachEnumerator. . :: . .GetEnumerator(Connections, VariableDispenser, IDTSInfoEvents, IDTSLogging)。）
	GetHashCode	Returns the hash code for this instance. （从 DtsObject 继承。）
	GetType	（从 Object 继承。）
	ImportXML	Imports XML into the collection.
	InitializeForEachEnumerator	Initializes the properties associated with the task. This method is called by the runtime and is not used in code. （从 ForEachEnumerator 继承。）
	MemberwiseClone	（从 Object 继承。）
	ToString	（从 Object 继承。）
	Update	This method updates the old package XML with the new package XML if CanUpdate is set to true. （从 ForEachEnumerator 继承。）
	Validate	Allows the container to determine if it contains invalid settings that will prevent it from executing successfully. （从 ForEachEnumerator 继承。）

注释

This class allows access to the enumerator items directly without calling GetEnumerator. This interface also allows the enumerator to have data added to its collection. Additionally, it has ImportXML and ExportXML methods that allow the enumerator to read and write data to an .xml file.
