游戏是全屏还是窗口？

Question

Is there anyway to know if a certain game is running on full screen or running as a window?

I need this because my application is for a game that can toggle between fullscreen and window mode and I need to act differently to each situation.

something like:

if (Fullscreen) {Act For Fullscreen} else {Act For Window Mode}

*The game isn't mine, it's another game. A real game.

Answer 1

I assume that game is not written by you. You can use Win32 api http://www.pinvoke.net/default.aspx/user32.GetWindowPlacement

Answer 2

won't this do?

if(WindowState == WindowState.Maximized)

Answer 3

It will probably depend on specific graphics technology you will be using rather than on WinForms API.

For example XNA (DirectX):

GraphicsDeviceManager graphics = new GraphicsDeviceManager(...); 

graphics.IsFullScreen = true; 

Answer 4

Have you looked at the WindowState and FormWindowState enumeration?

A Full Screen application is a maximized window without borders.
