介绍

框架使用.NET452；

Visual Studio 2019;

项目使用MIT开源许可协议；

更多效果可以通过GitHub[1]|码云[2]下载代码;

也可以自行添加天气信息等。

正文

屏保程序的本质上就是一个Win32窗口应用程序；

把编译好一个窗口应用程序之后，把扩展名更改为scr，于是你的屏幕保护程序就做好了;

选中修改好的scr程序上点击右键，可以看到一个安装选项，点击之后就安装了;

安装之后会立即看到我们的屏幕保护程序已经运行起来了;

处理屏幕保护程序参数如下

/s屏幕保护程序开始，或者用户点击了预览按钮;

/c用户点击了设置按钮;

/p用户选中屏保程序之后，在预览窗格中显示;

实现代码

1）MainWindow.xaml代码如下;

<Window x:Class="ScreenSaver.MainWindow"         xmlns="schemas.microsoft.com/winfx/2006/xaml/presentation"         xmlns:x="schemas.microsoft.com/winfx/2006/xaml"         xmlns:d="schemas.microsoft.com/expression/blend/2008"         xmlns:mc="schemas.openxmlformats.org/markup-compatibility/2006"         xmlns:system="clr-namespace:System;assembly=mscorlib"         xmlns:drawing="www.microsoft.net/drawing"         xmlns:local="clr-namespace:ScreenSaver"         mc:Ignorable="d" WindowStyle="None"         Title="MainWindow" Height="450" Width="800">     <Grid x:Name="MainGrid">         <drawing:PanningItems ItemsSource="{Binding stringCollection,RelativeSource={RelativeSource AncestorType=local:MainWindow}}"                               x:Name="MyPanningItems">             <drawing:PanningItems.ItemTemplate>                 <DataTemplate>                     <Rectangle>                         <Rectangle.Fill>                             <ImageBrush ImageSource="{Binding .}"/>                         </Rectangle.Fill>                     </Rectangle>                 </DataTemplate>             </drawing:PanningItems.ItemTemplate>         </drawing:PanningItems>         <Grid  HorizontalAlignment="Center"                 VerticalAlignment="Top"                 Margin="0,50,0,0">             <Grid.RowDefinitions>                 <RowDefinition/>                 <RowDefinition/>             </Grid.RowDefinitions>             <Grid.Resources>                 <Style TargetType="TextBlock">                     <Setter Property="FontSize" Value="90"/>                     <Setter Property="FontWeight" Value="Black"/>                     <Setter Property="Foreground" Value="White"/>                 </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">                             <BeginStoryboard>                                 <Storyboard>                                     <DoubleAnimation Duration="00:00:01"                                                  From="1"                                                  To="0"                                                  Storyboard.TargetName="PART_TextBlock"                                                  Storyboard.TargetProperty="Opacity"                                                  RepeatBehavior="Forever"                                                  FillBehavior="Stop"/>                                 </Storyboard>                             </BeginStoryboard>                         </EventTrigger>                     </TextBlock.Triggers>                 </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代码如下;

当屏保启动后需要注意如下

• 将鼠标设置为不可见Cursors.None;
• 将窗体设置为最大化WindowState.Maximized;
• WindowStyle设置为"None";
• 注意监听鼠标按下和键盘按键则退出屏保;
