Required Permissions

ReadProperties on Item

The ListChildren 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 the ListChildren 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 ListChildren is called on the root.

The ListChildren 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 報表伺服器項目屬性.

範例

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:

Imports System
Imports System.IO
Imports System.Text
Imports System.Web.Services.Protocols
Imports System.Xml
Imports System.Xml.Serialization
