How to print a PDF with C#

Question

I´ve trying to solve this problem for nearly 2 days. There are a lot of more or fewer good solutions on the net, but not a single one fits my task perfectly.

You can use ghostscript to convert PDF into image formats.

The following example converts a single PDF into a sequence of PNG-Files:

private static void ExecuteGhostscript(string input, string tempDirectory)
{
    // %d will be replaced by ghostscript with a number for each page
    string filename = Path.GetFileNameWithoutExtension(input) + "-%d.png";
    string output = Path.Combine(tempDirectory, filename);

    Process ghostscript = new Process();
    ghostscript.StartInfo.FileName = _pathToGhostscript;
    ghostscript.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;

    ghostscript.StartInfo.Arguments = string.Format(
        "-dSAFER -dBATCH -dNOPAUSE -sDEVICE=png16m -r300 -sOutputFile=\"{0}\" \"{1}\"", output, input);

    ghostscript.Start();
    ghostscript.WaitForExit();
}

If you prefer to use Adobe Reader instead you can hide its window:

process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
