Could you post the mapfile you have used?

You have created shapefileObj with mode = 5. This setting will create
a new empty shapefile by default. Use -1 as the mode parameter if you
want to open an existing file.

Have you set WEB.IMAGEPATH and WEB.IMAGEURL in you map file?

What do you mean? For a description of the SWIG mapscript API visit:
http://mapserver.gis.umn.edu/docs/reference/mapscript
For the C# specific issues see:
http://mapserver.gis.umn.edu/docs/howto/mapscriptcscompile

My plan is to have the C# API fully supported for the ASP.NET
application models.
To achieve this we should reconsider how mapserver supports the
execution of the multiple threads. For more details see:

http://mapserver.gis.umn.edu/docs/faq/thread_safety
http://mapserver.gis.umn.edu/development/rfc/ms-rfc-15

These issues also apply to the other languages having multiple threads
executed simultaneously.

Best Regards,
