Osservazioni

The DependencyTree object represents a SQL Server object that also references child and sibling SQL Server objects. The references to child and sibling objects are represented by DependencyTreeNode objects. The SQL Server objects that the DependencyTree object and DependencyTreeNode objects represent can be obtained using the Urn property. The DependencyTree object can be navigated using the various properties such as FirstChild and NextSibling or by using the WalkDependencies method of the DependencyWalker object.
