public function ListChildren(
ItemPath : String,
Recursive : boolean
) : CatalogItem[]
Parameter
- ItemPath
Typ: System.String
The full path name of the parent folder.
- Recursive
Typ: System.Boolean
A Boolean expression that indicates whether to return the entire tree of child items below the specified item. The default value is false.Note Setting this parameter to true in SharePoint mode can significantly reduce the performance of your application.
Rückgabewert
Typ: array<ReportService2010.CatalogItem[]
An array of CatalogItem objects. If no children exist, this method returns an empty array.

This method returns only child items that the user has permission to view. The items that are returned may not represent a complete list of child items of the specified parent item.
If this method is called on the root of the report server database with My Reports enabled, the method returns an array of CatalogItem objects containing properties for the folder My Reports. If the user is anonymous and My Reports is enabled, the properties for My Reports are not returned when this method is called on the root.
This method can return the VirtualPath property of items in the report server database that support virtual paths. The virtual path is the path under which a user expects to see the item. For example, a report called "Report1" located in the user's personal My Reports folder has a virtual path equal to "/My Reports". The actual path of the item is /Users/Username/My Reports.
The majority of the properties this method returns are read-only. For more information about item properties in Reporting Services, see Eigenschaften der Berichtsserverelemente.

To compile the following code example, you must reference the Reporting Services WSDL and import certain namespaces. For more information, see Compiling and Running Code Examples. The following code example uses the ListChildren method to read the contents of the root of the report server directory tree, and then stores the first item and its properties as an XML document:
