Deleting Metabase Nodes Using System.DirectoryServices

You can delete a metabase node such as a virtual directory to remove it from an IIS server. Deleting a metabase node changes only the configuration of the server. It does not delete the content files and DLLs that are stored in the physical path that is mapped to the virtual directory.

Example Code

The following example shows you how to use the C# programming language to delete a node in the IIS metabase. In this case, the node is a Web site with the identifier of 555. To see an example of code that creates a Web site, see Creating Sites and Virtual Directories Using System.DirectoryServices.

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

  //    or "IIS://localhost/W3SVC/AppPools/MyAppPool"
  Console.WriteLine("\nDeleting {0}:", metabasePath);
