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;

<Windowx: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">
<Gridx:Name="MainGrid">
<drawing:PanningItemsItemsSource="{BindingstringCollection,RelativeSource={RelativeSourceAncestorType=local:MainWindow}}"
x:Name="MyPanningItems">
<drawing:PanningItems.ItemTemplate>
<DataTemplate>
<Rectangle>
<Rectangle.Fill>
<ImageBrushImageSource="{Binding.}"/>
</Rectangle.Fill>
</Rectangle>
</DataTemplate>
</drawing:PanningItems.ItemTemplate>
</drawing:PanningItems>
<GridHorizontalAlignment="Center"
VerticalAlignment="Top"
Margin="0,50,0,0">
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<Grid.Resources>
<StyleTargetType="Textblock">
<SetterProperty="FontSize"Value="90"/>
<SetterProperty="FontWeight"Value="Black"/>
<SetterProperty="Foreground"Value="White"/>
</Style>
</Grid.Resources>
<WrapPanel>
<TextBlockText="{BindingHour,RelativeSource={RelativeSourceAncestorType=local:MainWindow}}"/>
<TextBlockText=":"x:Name="PART_TextBlock">
<TextBlock.Triggers>
<EventTriggerRoutedEvent="FrameworkElement.Loaded">
<BeginStoryboard>
<Storyboard>
<DoubleAnimationDuration="00:00:01"
From="1"
To="0"
Storyboard.TargetName="PART_TextBlock"
Storyboard.TargetProperty="Opacity"
RepeatBehavior="Forever"
FillBehavior="Stop"/>
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</TextBlock.Triggers>
</TextBlock>
<TextBlockText="{BindingMinute,RelativeSource={RelativeSourceAncestorType=local:MainWindow}}"/>
</WrapPanel>
<TextBlockGrid.Row="1"FontSize="45"HorizontalAlignment="Center"Text="{BindingDate,RelativeSource={RelativeSourceAncestorType=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

usingSystem;
usingSystem.Collections.ObjectModel;
usingSystem.Globalization;
usingSystem.IO;
usingSystem.Windows;
usingSystem.Windows.Input;
usingSystem.Windows.Threading;

namespaceScreenSaver
{
///<summary>
///MainWindow.xaml的交互逻辑
///</summary>
publicpartialclassMainWindow:Window
{
publicstaticreadonlyDependencyPropertystringCollectionProperty=
DependencyProperty.Register("stringCollection",typeof(ObservableCollection<string>),typeof(MainWindow),
newpropertyMetadata(null));

publicstaticreadonlyDependencyPropertyHourProperty=
DependencyProperty.Register("Hour",typeof(string),typeof(MainWindow),newPropertyMetadata(null));

publicstaticreadonlyDependencyPropertyMinuteProperty=
DependencyProperty.Register("Minute",typeof(string),typeof(MainWindow),newPropertyMetadata(null));

publicstaticreadonlyDependencyPropertySecondProperty=
DependencyProperty.Register("Second",typeof(string),typeof(MainWindow),newPropertyMetadata(null));

publicstaticreadonlyDependencyPropertyDateProperty=
DependencyProperty.Register("Date",typeof(string),typeof(MainWindow),newPropertyMetadata());

privatereadonlyDispatcherTimertimer=newDispatcherTimer();

publicMainWindow()
{
InitializeComponent();
Loaded+=delegate
{
WindowState=WindowState.Maximized;
Mouse.OverrideCursor=Cursors.None;
vardate=DateTime.Now;
Hour=date.ToString("HH");
Minute=date.ToString("mm");
Date=
$"{date.Month}/{date.Day}{CultureInfo.CurrentCulture.DateTimeFormat.GetDayName(date.DayOfWeek)}";
stringCollection=newObservableCollection<string>();
varpath=Path.Combine(AppDomain.CurrentDomain.BaseDirectory,"Images");
vardirectoryInfo=newDirectoryInfo(path);
foreach(varitemindirectoryInfo.GetFiles())
{
if(Path.GetExtension(item.Name)!=".jpg")continue;
stringCollection.Add(item.FullName);
}

timer.Interval=TimeSpan.FromSeconds(1);
timer.Tick+=delegate
{
date=DateTime.Now;
Hour=date.ToString("HH");
Minute=date.ToString("mm");
Date=
$"{date.Month}/{date.Day}{CultureInfo.CurrentCulture.DateTimeFormat.GetDayName(date.DayOfWeek)}";
};
timer.Start();
};
MouseDown+=delegate{Application.Current.Shutdown();};
KeyDown+=delegate{Application.Current.Shutdown();};
}

publicObservableCollection<string>stringCollection
{
get=>(ObservableCollection<string>)GetValue(stringCollectionProperty);
set=>SetValue(stringCollectionProperty,value);
}


publicstringHour
{
get=>(string)GetValue(HourProperty);
set=>SetValue(HourProperty,value);
}

publicstringMinute
{
get=>(string)GetValue(MinuteProperty);
set=>SetValue(MinuteProperty,value);
}

publicstringSecond
{
get=>(string)GetValue(SecondProperty);
set=>SetValue(SecondProperty,value);
}


publicstringDate
{
get=>(string)GetValue(DateProperty);
set=>SetValue(DateProperty,value);
}
}
}
