    The   following   table   lists   data   types   used   in   the   Win32   API   (listed   in   Wtypes.h)   and   C-style   functions.   Many   unmanaged   libraries   contain   functions   that   pass   these   data   types   as   parameters   and   return   values.   The   third   column   lists   the   corresponding   .NET   Framework   built-in   value   type   or   class   that   you   use   in   managed   code.   In   some   cases,   you   can   substitute   a   type   of   the   same   size   for   the   type   listed   in   the   table.
