ForEachEnumeratorHost 型別公開下列成員。

屬性

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

方法

	名稱	說明
	Equals	Determines whether two object instances are equal. (繼承自 DtsObject。)
	GetEnumerator	Returns an IEnumerator interface for use in iterating over the ForEachEnumerator.
	GetExecutionPath	Gets the execution path for the ForEachEnumeratorHost object.
	GetExpression	Returns a String that contains the expression for the specified property. Null means no expression is assigned.
	GetHashCode	Returns the hash code for this instance. (繼承自 DtsObject。)
	GetPackagePath	Gets the package path for the ForEachEnumeratorHost object.
	GetType	(繼承自 Object。)
	LoadFromXML	This method is not callable by your application code. To load a package saved as .xml, use the Application.LoadPackage method.
	SaveToXML	This method is not callable by your application code. To save a package as .xml, use the Application.SaveToXml method.
	SetExpression	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	Allows the host to determine if there are invalid settings that will prevent the ForEachEnumerator from executing successfully.
