最近在网上爬了一些漂亮小姐姐做壁纸,虽然大多都是喜欢的,难免也有不喜欢的,都过一遍工作量也太大了,我就想有没有方法,在用文件夹幻灯片自动切换壁纸的时候,遇到不喜欢的可以删掉呢?这样用上一段时间,剩下的就都是我的喜欢的了,可是除了学C的时候,后来基本都没有写过exe程序了,也没有做过windows的相关开发,api调用也是完全懵逼的.后来经过一番百度和cv大法,终于用c#实现了.目的勉强达到,还是有点意思的.哈哈😄.

}
}
}
编译用csc .\AutoChangeWallpaper.cs /r:Microsoft.VisualBasic.dll就可以编译出exe执行了.
运行
输入 d 回车就可以删除当前图片了.
很简单的小玩意儿,能拼出来还是有点意外的. 嗯嗯,就是这样,该吃饭了.😄
