属性

	名称	说明
	CollectionEnumerator	Returns a Boolean indicating whether the enumerator type is an element collection. （覆盖 ForEachEnumerator. . :: . .CollectionEnumerator。）
	EnumerationType	Gets or sets this property to a value from the EnumerationType enumeration.
	InnerElementType	Gets or sets this property to a value from the InnerElementType enumeration.
	InnerXPathString	Specifies the XPath string, or the name of the variable containing the XPath string, depending on the value of InnerXPathStringSourceType.
	InnerXPathStringSourceType	Gets or sets the source type of the inner XPath string using values from the SourceType enumeration.
	NodeList	Gets an ArrayList class that contains a collection of nodes that the XPath operation produces.
	OuterXPathString	Get or sets a value that represents either the XPath string, the name of the file containing the XPath string, or the name of the variable containing the XPath string, depending on the value of OuterXPathStringSourceType.
	OuterXPathStringSourceType	Gets or sets the source type of the XPath string, using values in the SourceType enumeration.
	SourceDocument	Gets or sets a value that represents either the XML source document as a string, the name of the file containing the XML source document, or the name of the variable containing the XML source document, depending on the value of SourceDocumentType.
	SourceDocumentType	Gets or sets the type of source that the source document is, using the SourceType enumerator.
	Version	Returns the version number of the package. This property is read-only. （从 ForEachEnumerator 继承。）

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。）
	Finalize	（从 Object 继承。）
	GetEnumerator	Returns an enumerator that can iterate through the ForEachNodeListEnumerator instance. （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。）
	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。）
	LoadFromXML	This method is not callable by your application code. To load a package saved as .xml, use the Application..::..LoadPackage method.
	MemberwiseClone	（从 Object 继承。）
	SaveToXML	This method is not callable by your application code. To save a package as .xml, use the Application..::..SaveToXml method.
	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。）
