有没有办法可以在C＃中更改Windows 10后台设置？

问题描述：

我想更改Windows - >幻灯片显示的背景设置，并设置包含我的图像的目录路径。这样桌面图像就会以幻灯片形式开始变化。

我尝试过的事情：

I want to change the Windows -> Background settings to Slideshow and set a directory path containing my images. So that the desktop images start changing as slideshow.

What I have tried:

I found the following registry keys 

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Wallpapers

key : <pre>SlideshowDirectoryPath1

和

and

Computer\HKEY_CURRENT_USER\Control Panel\Desktop

key：

key :

WallPaper

我也尝试过这个方法..它更新壁纸，但我正在寻找一种方法将其更改为幻灯片。

win32.SystemParametersInfo（SET_DESKTOP_BACKGROUND，0，sFile_FullPath，UPDATE_INI_FILE | SEND_WINDOWS_INI_CHANGE）;

任何帮助将不胜感激..谢谢。

I have also tried this method .. it updates the wallpaper but i am looking for a way to change it to slideshow.
win32.SystemParametersInfo(SET_DESKTOP_BACKGROUND, 0, sFile_FullPath, UPDATE_INI_FILE | SEND_WINDOWS_INI_CHANGE);

Any help will be greatly appreciated .. Thanks.

答

你需要的两个设置：

Two settings in there you need:

SlideshowDirectoryPath1
SlideshowSourceDirectorySet

后者很简单：1

前者更难，因为它不是一个直文件夹，它是加密的。

所以

The later is simple: 1
The former is harder, because it isn't a "straight" folder, it's encrypted.
So

D:\Pictures\Wallpaper\Chinese paintings

结果为

Comes out as

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

其中是BASE64 PIDL显然。

我没有和他们玩过，所以这一点会由你决定，但这里有一些代码应该有所帮助：保存照片屏幕保护程序设置在哪里？ [ ^ ] - Powershell代码大约下降了1/2，但这应该很容易转换为C＃。或者有一个命令shell命令将它插入到可能更容易使用的代码下面！

然后你需要在

Which is a BASE64 PIDL apparently.
I've not played with them, so that bit's going to be up to you, but there is some code here that should help: Where are Photo Screensaver settings saved?[^] - the Powershell code is about 1/2 way down, but that should translate to C# reasonably easily. Or there is a command shell command to insert it below that code that might be easier to use!

You then need to set the values under

Computer\HKEY_CURRENT_USER\Control Panel\Personalization\Desktop Slideshow

使幻灯片显示工作。
