I want to read and view dxf file using C#. I searched on the internet
and found some result in codeproject.com but that working not well. So
I found some dll file to support this but it is of commercial .
Someone please help me or give some examples about this?

You're going to have a hard time finding anything to deal with AutoCAD
that is, at the same time

1) Good
2) Not commerical

There's just too high a percentage of AutoCAD users that HAVE money, to
make it reasonable to expect good, free/low-cost stuff. There are more
specific problems too, which you can read about in excellent responses
to this concept at:

and

DWG is a lot tougher to deal with than DXF, given that it's encrypted
and changes spec every 3 years. On the other hand, reading and writing
DXF files really isn't a problem. Just use a streamwriter! I mean,
they're just text files.

Now, if you want to parse, or display, or manipulate them, that might
be more difficult. :)

http://www.opendesign.com/the_oda_platform/dwgdirect.net and
http://through-the-interface.typepad.com/ are two places that those
answers in StackOverflow pointed me at. They look intriguing.

A quick search on "DXF C#" pointed me at
http://www.sharewareconnection.com/2d-3d-dxf-import-net.htm as well.

Good luck! If you make any progress and actually have details on what
you're doing, feel free to come back and share.
