I want execute ImageMagick from c#

[nikaan]

How can I build *.dll with Main function Main(Sring arg[])?
I need a few functions from ImageMagick :

convert 1.tif -normalize 1.jpg

convert '*.jpg' -resize 120x120 thumbnail%03d.jpg

convert 1.jpg +level-colors Blue,Yellow 2.jpg

convert 1.jpg -sigmoidal-contrast 4,0% 2.jpg

convert 1.jpg 2.jpg 3.jpg -combine c.jpg

Could you help me?

It will be greatful if I may deliver reference without nemes of files
for example main("convert", *image, string, *image)...

I build solution in VS, but I do not know which from *.dll is needed.

I can't use .exe - but for test-version I wrote *.bat and all works.
