ForEachSchemaRowsetEnumerator 类型公开以下成员。

构造函数

	名称	说明
	ForEachSchemaRowsetEnumerator	Initializes a new instance of the ForEachSchemaRowsetEnumerator class.

页首

属性

	名称	说明
	CollectionEnumerator	Gets or sets Boolean that indicates if the foreach loop enumerator is enumerating collections of objects or enumerating collections of collections. （从 ForEachEnumerator 继承。）
	Connection	Gets or sets a String that contains the connection information for the schema rowset enumerator.
	ForEachEnumeratorDescription	Returns a description for the ForEachSchemaRowsetEnumerator.
	ForEachEnumeratorDisplayName	Gets or sets a String that contains the display name for the enumerator.
	Restrictions	Gets or sets an array of Strings that contains the restrictions to apply to the rowset that is returned.
	SchemaRowset	Gets or sets the GUID of the schema
	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。）
	GetEnumerator	Returns an enumerator for iterating over the 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。）
	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.
	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。）
