Moving or Copying Metabase Nodes Using Absolute ADsPaths

Artículo
06/16/2017

Move or copy metabase nodes when you want to perform configuration tasks such as moving a virtual directory from one Web site to another or copying in bulk the configuration of one node to another.

Example Code

The following example shows you how to use the C# programming language to create a new virtual directory called "MyVDir" in the default Web site, copy it to a new virtual directory called "MyVDir2", then move "MyVDir2" to "MyVDir3". Code is also included to delete the new nodes.

This example requires Windows XP Professional Service Pack 2 or Windows Server 2003 Service Pack 1.

Note

System.DirectoryServices can be used to get and set String and DWORD properties in the IIS metabase, and invoke most methods. However, you cannot move or copy metabase nodes unless you are using Windows XP Professional with Service Pack 2 or Windows Server 2003 with Service Pack 1.

To keep this code example concise, it does not include code access security (CAS) parameters or parameter checking. For more information, see Code Access Security and Validating User Input to Avoid Attacks. Additionally, you can instantiate your System.DirectoryServices.DirectoryEntry object with an authentication parameter.
