How to Get Running Application with C# Windows Service

Question

I've build a Windows service with C# which get all running applications on my computer (Notepad,...). I've tryed this following code but it doesn't work :

Thank you all for your help!

Process[] processes = Process.GetProcesses();
using (TextWriter tw = new StreamWriter(@"C:\Users\Public\Documents\Info.txt"))
{
  foreach(Process p in processes)
  {
    if(!String.IsNullOrEmpty(p.MainWindowTitle))
    {
      tw.WriteLine(p.MainWindowTitle);
    }
  }
}

Thank you for replying! It shows nothing. I think, may be the Windows Service can't interact with "MainWindowTitle". Because i've tryed this code with Windows form and it works. — Lama, Jan 08 '19 at 07:48

That's why you are checking MainWindowTitle on your code. You have to know MainWindowTitle has value just for those processes which they have GUI like notepad or skype or ...

To identify all the process name it's better to check ProcessName property to get the process name.

So I recommend you to change your code like this:

using (TextWriter tw = new StreamWriter(@"C:\Users\Public\Documents\Info.txt"))
{
    foreach (Process p in processes)
    {
        if (!String.IsNullOrEmpty(p.ProcessName))
        {
            var processTitle= !string.IsNullOrEmpty(p.MainWindowTitle) ? p.MainWindowTitle: "N/A";
            tw.WriteLine(string.Format("Process Name: {0} \t\t Process GUI Title:{1}",p.ProcessName, processTitle));
        }
    }
}
