VirtualPathProvider.DirectoryExists Method

Gets a value that indicates whether a directory exists in the virtual file system.

Assembly:  System.Web (in System.Web.dll)

public function DirectoryExists(
	virtualDir : String
) : boolean

Parameters

virtualDir
Type: System.String

The path to the virtual directory.

Return Value

Type: System.Boolean
true if the directory exists in the virtual file system; otherwise, false.

Override the DirectoryExists method to indicate to the compilation system that the resource represented by virtualDir exists in the virtual file system provided by this VirtualPathProvider instance.

If your custom VirtualPathProvider class does not support directories, the DirectoryExists method should return false.

NoteNote:

If your virtual file system will contain themes for the Web site (by creating a virtual App_Themes directory), your custom VirtualPathProvider class must support directories.

The following code example is an implementation of the DirectoryExists method in a custom VirtualPathProvider class. For the full code required to run the example, see the Example section of the VirtualPathProvider class overview topic.
