I have a C# project. This project needs to convert PDF file into an image file. Except for a few single-page PDF files, many of my PDF files are with multiple pages. So I may need to convert multi-page PDF file into an image which needs to contain all pages of the PDF document.

Firstly, i tried to use Acrobat.dll in my C# project but it had to install Adobe Acrobat. This is not what I want.

I tried to find a solution from Google, but many tools are quite expensive. I am a personal developer, so the expensive development costs are not affordable for me.
