How can I get Application name? in c#

Question

I used following code to get windows title but for application name p1 returns devenv instead of Visual Studio
If anyone knows how to resolve this issue, please let know

        var wnd = GetForegroundWindow();
        uint procId;
        GetWindowThreadProcessId(wnd, out procId);

        var p = Process.GetProcessById((int)procId).MainWindowTitle.ToString();
        var p1 = Process.GetProcessById((int)procId).ProcessName.ToString();


        string shortDateString = DateTime.Now.ToShortDateString();


        List<string> app = new List<string>();
        app.Add(p);

Answer 1

For example :

var p = Process.GetProcessById((int)procId).MainModule.FileName;
FileVersionInfo fvi = FileVersionInfo.GetVersionInfo(p);
string sDescription = fvi.FileDescription;
