ForEachEnumeratorHostClass 类型公开以下成员。

构造函数

	名称	说明
	ForEachEnumeratorHostClass	基础结构。Initializes a new instance of the ForEachEnumeratorHostClass class.

页首

属性

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

方法

	名称	说明
	ComputeExpressions	基础结构。Computes the expressions in the property collection.
	Equals	（从 Object 继承。）
	Finalize	（从 Object 继承。）
	GetEnumerator	基础结构。Returns an IEnumerator interface for use in iterating over the ForEachItemEnumeratorClass.
	GetExpression	基础结构。Returns a String that contains the expression for the specified property. Null means no expression is assigned.
	GetHashCode	（从 Object 继承。）
	GetType	（从 Object 继承。）
	InitializeForEachEnumerator	基础结构。Initializes the properties associated with the task.
	MemberwiseClone	（从 Object 继承。）
	SetExpression	基础结构。Assigns the specified expression to the property. Specify nullnull 引用（在 Visual Basic 中为 Nothing） to remove an existing expression from the property.
	ToString	（从 Object 继承。）
	Validate	基础结构。Allows the host to determine if there are invalid settings that will prevent the ForEachItemEnumeratorClass from executing successfully.
