How to convert PDF to images using C # and ImageMagick?

Question

I would like to convert a PDF file to .GIF using C # and magicknet.dll. I added a link to the MagickNet Dll file to my project.

MagickNet.Magick.Init(); MagickNet.Image img = new MagickNet.Image("d:/aa.pdf"); img.Write("d:/bb.gif"); MagickNet.Magick.Term(); img.Dispose(); 

  System.Runtime.InteropServices.SEHException was unhandled by user code
   Message = "External component has thrown an exception."
   Source = "ImageMagickNET"
   ErrorCode = -2147467259
   Stacktrace:

ImageMagick requires GhostScript to interpret PDF files. If you want, you can directly call the GhostScript DLL (contact me through my profile, I will send you a C # wrapper)

Alternatively, you can use the GhostScript command line or a commercial third-party component, such as the PDF libraries from Tall Components.
