c# - Taskbar location

Question

How can i detect where the taskbar is located? I need to know for displaying my notification in the right corner. Thanks

Edit: Thank you Hans Passant. I used that with this to get location. I hope is ok.

GetTaskbarLocation(TaskbarPosition.GetTaskbarPosition());

private void GetTaskbarLocation(Rectangle rc)
{
    if (rc.X == rc.Y)
    {
        if (rc.Right < rc.Bottom)
            taskbarLocation = TaskbarLocation.Left;
        if (rc.Right > rc.Bottom)
            taskbarLocation = TaskbarLocation.Top;
    }
    if (rc.X > rc.Y)
        taskbarLocation = TaskbarLocation.Right;
    if (rc.X < rc.Y)
        taskbarLocation = TaskbarLocation.Bottom;
}

    public static Rectangle GetTaskbarPosition() {
        var data = new APPBARDATA();
        data.cbSize = System.Runtime.InteropServices.Marshal.SizeOf(data);
        IntPtr retval = SHAppBarMessage(ABM_GETTASKBARPOS, ref data);
        if (retval == IntPtr.Zero) throw new Win32Exception("Please re-install Windows");
        return new Rectangle(data.rc.left, data.rc.top,
            data.rc.right - data.rc.left, data.rc.bottom - data.rc.top);

    }

    // P/Invoke goo:
    private const int ABM_GETTASKBARPOS = 5;
    [System.Runtime.InteropServices.DllImport("shell32.dll")]
    private static extern IntPtr SHAppBarMessage(int msg, ref APPBARDATA data);
    private struct APPBARDATA {
        public int cbSize;
        public IntPtr hWnd;
        public int uCallbackMessage;
        public int uEdge;
        public RECT rc;
        public IntPtr lParam;
    }
    private struct RECT {
        public int left, top, right, bottom;
    }
