How to get Windows explorer’s position using .net?

I am developing an application which triggers when there is a windows explorer window in foreground. My application triggers a window (form) which will be placed on screen near the opened windows explorer (Planning to keep it just below the search option).

But I am not getting anything to get the window position of foreground "windows explorer" window.

Is there any way to read the position of current foreground “Windows Explorer” window using .net?

You can do this by using unmanaged code.

Create a class:

    class RectMethods
    {
        // http://msdn.microsoft.com/en-us/library/ms633519(VS.85).aspx
        [DllImport("user32.dll", SetLastError = true)]
        [return: MarshalAs(UnmanagedType.Bool)]
        public static extern bool GetWindowRect(IntPtr hWnd, ref RECT lpRect);

        // http://msdn.microsoft.com/en-us/library/a5ch4fda(VS.80).aspx
        [StructLayout(LayoutKind.Sequential)]
        public struct RECT
        {
            public int Left;
            public int Top;
            public int Right;
            public int Bottom;
        }
    }

Then, identify the explorer process to pick up your handle, and take the coordinates and the size of the window, and from there you can do what you want:

            var processes = System.Diagnostics.Process.GetProcesses();
            foreach (var process in processes)
            {
                if (process.ProcessName == "explorer")
                {
                    var hWnd = process.Handle;
                    RectMethods.RECT rect = new RectMethods.RECT();
                    if (RectMethods.GetWindowRect(hWnd, ref rect))
                    {
                        Size size = new Size(rect.Right - rect.Left,
                                 rect.Bottom - rect.Top);
                    }
                }
            }
