Examples

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);
}
Public Overrides Function GetDirectory(ByVal virtualDir As String) As VirtualDirectory
  If (IsPathVirtual(virtualDir)) Then
    Return New SampleVirtualDirectory(virtualDir, Me)
  Else
    Return Previous.GetDirectory(virtualDir)
  End If
End Function

Remarks

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.

Note

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.
