C# Class Microsoft.WindowsAzure.Commands.Tools.Vhd.VirtualDiskStream

Provides a logical stream over a virtual hard disk (VHD).

This stream implementation provides a "view" over a VHD, such that the VHD appears to be an ordinary fixed VHD file, regardless of the true physical layout. This stream supports any combination of differencing, dynamic disks, and fixed disks.
