屏保程序的本質(zhì)上就是一個(gè)Win32?窗口應(yīng)用程序。本文將利用WPF實(shí)現(xiàn)Windows屏保的制作，文中的示例代碼簡(jiǎn)潔易懂，對(duì)我們學(xué)習(xí)WPF有一定幫助，感興趣的可以了解一下

介紹

框架使用.NET452；

Visual Studio 2019;

項(xiàng)目使用 MIT 開(kāi)源許可協(xié)議；

更多效果可以通過(guò)GitHub[1]|碼云[2]下載代碼;

也可以自行添加天氣信息等。

屏保程序的本質(zhì)上就是一個(gè)Win32 窗口應(yīng)用程序；

把編譯好一個(gè)窗口應(yīng)用程序之后，把擴(kuò)展名更改為 scr，于是你的屏幕保護(hù)程序就做好了;

選中修改好的 scr 程序上點(diǎn)擊右鍵，可以看到一個(gè) 安裝選項(xiàng)，點(diǎn)擊之后就安裝了;

安裝之后會(huì)立即看到我們的屏幕保護(hù)程序已經(jīng)運(yùn)行起來(lái)了;

處理屏幕保護(hù)程序參數(shù)如下

/s 屏幕保護(hù)程序開(kāi)始，或者用戶點(diǎn)擊了 預(yù)覽 按鈕;

/c 用戶點(diǎn)擊了 設(shè)置按鈕;

/p 用戶選中屏保程序之后，在預(yù)覽窗格中顯示;

實(shí)現(xiàn)代碼

1）MainWindow.xaml 代碼如下;

<Window?x:Class="ScreenSaver.MainWindow"
????????xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

??????????????????????????????x:Name="MyPanningItems">
????????????<drawing:PanningItems.ItemTemplate>

????????????????</Style>
????????????</Grid.Resources>
????????????<WrapPanel>
????????????????<TextBlock?Text="{Binding?Hour,RelativeSource={RelativeSource?AncestorType=local:MainWindow}}"/>
????????????????<TextBlock?Text=":"?x:Name="PART_TextBlock">
????????????????????<TextBlock.Triggers>
????????????????????????<EventTrigger?RoutedEvent="FrameworkElement.Loaded">

????????????????????????????????</Storyboard>
????????????????????????????</BeginStoryboard>
????????????????????????</EventTrigger>

????????????????</TextBlock>
????????????????<TextBlock?Text="{Binding?Minute,RelativeSource={RelativeSource?AncestorType=local:MainWindow}}"/>
????????????</WrapPanel>
????????????<TextBlock?Grid.Row="1"?FontSize="45"?HorizontalAlignment="Center"?Text="{Binding?Date,RelativeSource={RelativeSource?AncestorType=local:MainWindow}}"/>
????????</Grid>
????</Grid>
</Window>

2） MainWindow.xaml.cs 代碼如下;

當(dāng)屏保啟動(dòng)后需要注意如下

將鼠標(biāo)設(shè)置為不可見(jiàn)Cursors.None;
將窗體設(shè)置為最大化WindowState.Maximized;
WindowStyle設(shè)置為"None";
注意監(jiān)聽(tīng)鼠標(biāo)按下和鍵盤(pán)按鍵則退出屏保;
