HELP FOR SEEKABLE NETWORK STREAMS IN .NET

[dany_gates]

hi,
Need some help on Network Streams in .NET. I m planning to build a .NET
application which
mimicks Download Accelerator Plus (DAP:famous downloading application). So
naturally i want to
incorporate features like "Pause" and "Resume" in my apps. But the Prob i
face here is .NET
namespace concerned with Internet usage i.e "System.NET" has a facility to
Download and Upload
files to/from Servers using many classes but none of them have Method with
which we can "Seek"
the position pointer of file to be downloaded to particular position! Even
the Methods which return
the Stream for downloading files, the returned Streams aren't "Seekable"! So
what i found is
that there isn't anyway that i can incorporate the "Pause" and "Resume"
functionality which
requires Seekable Streams using .NET Framework.
So i tried searching in "Native" Win SDK for help. And guess what! Win SDK's
some class
"CInternetSession" has a method called "Seek" which can reposition the
pointer of the file
to be downloaded. So i got the Solution. But i want my apps to be 100% .NET!
SO DOES ANYBODY HAVE ANY IDEA HOW CAN I GET SEEKABLE NETWORK STREAMS, OR
SEEK THE FILE
POINTER TO ANY PARTICULAR POSITION WITHIN THE FILE TO BE DOWNLOADED?
