VirtualPathProvider.GetDirectory Method

Gets a virtual directory from the virtual file system.

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

public virtual VirtualDirectory GetDirectory(
	string virtualDir
)

Parameters

virtualDir
Type: System.String
The path to the virtual directory.

Return Value

Type: System.Web.Hosting.VirtualDirectory
A descendent of the VirtualDirectory class that represents a directory in the virtual file system.

The GetDirectory method returns a descendent of the VirtualDirectory class that contains the file and directories contained in the directory specified in the virtualDir parameter.

If your custom VirtualPathProvider class does not support directories, the GetDirectory method should return null.

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 GetDirectory 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.


public override VirtualDirectory GetDirectory(string virtualDir)
{
  if (IsPathVirtual(virtualDir))
    return new SampleVirtualDirectory(virtualDir, this);
  else
    return Previous.GetDirectory(virtualDir);
}
