Question

I want to send different messages to specified window, but I do not konw how to identify a given window from all. Is the way to use the window’s property of “Name”?

Answer 1

You can create your own Window class

public class MyCoolWindow : Window
{
   public string WindowKey {get;set;}
}

and on every window create add a new window to a glbal collection, for exmaple:

var windows = new List<MyCoolWindow>(); 

public void AddAndShowWindow(MyCoolWindow wnd)
{        
    windows.Add(wnd);
    wnd.Show();
}

find window, for example

public MyCoolWindow FindWindowByKey(string windowKey)
{
    return windows.Where(w=>w.WindowKey == windowKey).SelectSingleOrDefault();
}

Just example.
