Getting the handle of window in C#

I have the following class declared:

public partial class MainWindow : Window

And I need to get the actual handle of the window once the window has one. How can I do that and where should I put the query function.

What I tried so far was:

IntPtr hwnd = new WindowInteropHelper(this).Handle;

But the handle I get back is 0, which might be because it was planted in OnInitialized - maybe the window is not ready yet at that stage. And, yes - it is connected via WPF, thank you for pointing it out!

Thanks

 [DllImport("user32.dll", EntryPoint = "FindWindowEx")]
        public static extern int FindWindowEx(int hwndParent, int hwndEnfant, int lpClasse, string lpTitre);


int hwnd = FindWindowEx(0, 0, 0, title);//where title is the windowtitle

                //verification of the window
                if (hwnd == 0)
                {
                    throw new Exception("Window not found");
                }
