WPF 程序最大化,窗口,最小化

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.WindowState = WindowState.Normal;
window.WindowStyle = WindowStyle.SingleBorderWindow;

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);
}

}

static void window_Deactivated(object sender, EventArgs e)
{
var window = sender as Window;
window.Topmost = false;
}

static void window_Activated(object sender, EventArgs e)
{
var window = sender as Window;
window.Topmost = true;
}

按需求,如果需要全屏后再还原窗口的话,就再全屏前记录窗口的属性

最小化后窗口也是一样,在最小化前记录窗口的属性,我这里直接给赋值了,
