WPF 最大化最小化窗口

public static void FullOrMin(this Window window)
        {
            //如果是全屏,则最小化
            if (window.WindowState == WindowState.Maximized)
            {
                window.Topmost = false;

                window.ResizeMode = ResizeMode.CanResizeWithGrip;//设置为可调整窗体大小
                window.Width = 800;
                window.Height = 600;

                //获取窗口句柄 
                var handle = new WindowInteropHelper(window).Handle;
                //获取当前显示器屏幕
                Screen screen = Screen.FromHandle(handle);

                window.Left = (screen.Bounds.Width - window.Width) / 2;
                window.Top = (screen.Bounds.Height - window.Height) / 2;

                window.WindowState = WindowState.Minimized;
                return;
            }

            //如果是窗口,则全屏
            if (window.WindowState == WindowState.Normal)
            {
                //变成无边窗体
                window.WindowState = WindowState.Normal;//假如已经是Maximized，就不能进入全屏，所以这里先调整状态
                window.WindowStyle = WindowStyle.None;
                window.ResizeMode = ResizeMode.NoResize;
                window.Topmost = true;//最大化后总是在最上面

                //获取窗口句柄 
                var handle = new WindowInteropHelper(window).Handle;

                //获取当前显示器屏幕
                Screen screen = Screen.FromHandle(handle);

                //调整窗口最大化,全屏的关键代码就是下面3句
                window.MaxWidth = screen.Bounds.Width;
                window.MaxHeight = screen.Bounds.Height;
                window.WindowState = WindowState.Maximized;

                //解决切换应用程序的问题
                window.Activated += new EventHandler(window_Activated);
                window.Deactivated += new EventHandler(window_Deactivated);
            }

        }
