How do I get the title of the current active window using c#?
I'd like to know how to grab the Window title of the current active window (i.e. the one that has focus) using C#.
See example on how you can do this with full source code here:
http://www.csharphelp.com/2006/08/get-current-window-handle-and-caption-with-windows-api-in-c/
[DllImport("user32.dll")]
static extern IntPtr GetForegroundWindow();
[DllImport("user32.dll")]
static extern int GetWindowText(IntPtr hWnd, StringBuilder text, int count);
private string GetActiveWindowTitle()
{
const int nChars = 256;
StringBuilder Buff = new StringBuilder(nChars);
IntPtr handle = GetForegroundWindow();
if (GetWindowText(handle, Buff, nChars) > 0)
{
return Buff.ToString();
}
return null;
}
Edited with @Doug McClean comments for better correctness.
If you were talking about WPF then use:
Application.Current.Windows.OfType<Window>().SingleOrDefault(w => w.IsActive);
