How do I get a list of "project names" from processes (not process name or window title)

Question

I'm looking for a way to list every process' application name. The ones like project names when you make a project in visual studio.

What I'm not looking for:

1. Window title

Process[] processes = Process.GetProcesses();
foreach (Process p in processes)
{
    if (!String.IsNullOrEmpty(p.MainWindowTitle))
    {
        Console.WriteLine(p.MainWindowTitle);
    }
}

2. Process name

Process[] processes = Process.GetProcesses();
foreach (Process p in processes)
{
    Console.WriteLine(p.ProcessName);
}

What I am looking for:

Entries in a task manager list:

Answer 1

While the p.MainModule throws for some processes (looking into it),

What you need can be achieved like this:

    Process p = Process.GetProcessesByName("winword")[0];
    string fileName = p.MainModule.FileName;

    FileVersionInfo myFileVersionInfo = FileVersionInfo.GetVersionInfo(fileName);

    // Writes "Microsoft Word"
    Console.Write(myFileVersionInfo.FileDescription);

EDIT 1:

It seems like the p.MainModule is not accessible if you run as 32 bit on a 64 bit environment.

When compiled to x64, all the process running with my user on my system could be displayed. For the others, elevation is probably required.
