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。

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="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:system="clr-namespace:System;assembly=mscorlib"
        xmlns:drawing="http://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;
