NoteNote:

This type is used by the .NET Framework for Silverlight. It cannot be used in Silverlight-based applications.

The Pack method transfers information from an Overlapped object to a NativeOverlapped structure that can be passed to Win32 API functions for asynchronous file I/O. The Unpack method transfers information from a NativeOverlapped structure to an instance of the Overlapped class.

Changes to the properties of an Overlapped object affect its associated NativeOverlapped structure, and vice versa.
