Terminate Adobe Acrobat in c#

[derndeh]

I am looping through and printing multiple pdf files. After I'm done printing, Adobe Acrobat is still running. I would like to find a way to shut it down. Here is the code within the loop:

Process p = new Process();
p.StartInfo.FileName = fileName;
p.StartInfo.CreateNoWindow = true;
p.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
p.StartInfo.Verb = "print";
p.Start();
p.Dispose();

I have tried to use:
p.Start();
p.WaitForExit(10000);
p.Kill();

This will kill acrobat, but it does so before all printing is complete. Is there a way to find any instance of Acrobat running and terminate it at any point I wish.
I have looked at MSDN and found an example to do this with notepad using Process.GetProcessById and thought of using Process.GetProcessByName("Acrobat.exe") but this does not return any process. Any Ideas?

Throw it into a console app, and loop through the Process.Threads. Watch their thread states, and find what changes after printing is done. Then create a watch for that, and kill it when that happens.

I've tried doing this. Maybe it is because of my lack of understanding on how to do this properly(very likely), but I wasn't able to find anything that would help me find the right time to kill the process. I have however figured out how using [DllImport("USER32.DLL")] I could find the running instance of Acrobat and use Sendkeys to send it Alt+F4. Thanks for the suggestion though.

this should work:

       Process process = new Process();
            process.StartInfo.FileName = filename;
            process.StartInfo.CreateNoWindow = true;
            process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
            process.StartInfo.Verb = "Print";
 
            process.Start();
 
            bool IsDone = false;
            while (!IsDone && !process.HasExited)
            {
                IsDone = true;
                process.Refresh();
                if (!process.HasExited)
                {
                    foreach (ProcessThread thread in process.Threads)
                    {
                        if (thread.ThreadState != System.Diagnostics.ThreadState.Terminated)
                            IsDone = false;
                    }
                }
            }
 
            if (!process.HasExited)
            {
                process.WaitForExit(1000);
                process.Kill();
            }
            process.Dispose();
