ForEachEnumeratorHostClass 型別公開下列成員。

建構函式

	名稱	說明
	ForEachEnumeratorHostClass	基礎結構。Initializes a new instance of the ForEachEnumeratorHostClass class.

上層

屬性

	名稱	說明
	CollectionEnumerator	基礎結構。Gets or sets a Boolean that indicates if the hosting enumerator is enumerating collections of objects or enumerating collections of collections.
	CreationName	基礎結構。Returns the string that is used by the run-time to create an instance of the ForEachItemEnumeratorClass object. This property is read-only.
	DelayValidation	基礎結構。Gets or sets a Boolean that indicates whether ForEachItemEnumeratorClass validation is delayed until the package runs.
	Description	基礎結構。Gets or sets description for the host.
	HostType	基礎結構。Gets an enumeration that describes the type of host that the ForEachItemEnumeratorClass is being used by. This property is read-only.
	ID	基礎結構。Returns the GUID assigned to the host.
	InnerObject	基礎結構。Returns the inner object of the host, which is the ForEachItemEnumeratorClass that is being hosted.
	Name	基礎結構。Gets or sets a name for the host.
	Properties	基礎結構。Returns a IDTSProperties100 collection that contains IDTSProperty100 objects. Each IDTSProperty100 has additional information about each task in the ForEachItemEnumeratorClass.

	名稱	說明
	ComputeExpressions	基礎結構。Computes the expressions in the property collection.
	Equals	(繼承自 Object。)
	Finalize	(繼承自 Object。)
	GetEnumerator	基礎結構。Returns an IEnumerator interface for use in iterating over the ForEachItemEnumeratorClass.
	GetExpression	基礎結構。Returns a String that contains the expression for the specified property. Null means no expression is assigned.
	GetHashCode	(繼承自 Object。)
	GetType	(繼承自 Object。)
	InitializeForEachEnumerator	基礎結構。Initializes the properties associated with the task.
	MemberwiseClone	(繼承自 Object。)
	SetExpression	基礎結構。Assigns the specified expression to the property. Specify nullnull 參考 (在 Visual Basic 中為 Nothing) to remove an existing expression from the property.
	ToString	(繼承自 Object。)
	Validate	基礎結構。Allows the host to determine if there are invalid settings that will prevent the ForEachItemEnumeratorClass from executing successfully.
