推荐答案

所以你的问题是你的应用程序没有适当的权限访问c：\ usersrs \ inconnu \documents\ma音乐。您的第一个屏幕截图仅显示文档文件夹的快捷方式（这没有多大帮助）。



这里的解决方案是以管理员权限运行代码，如图用户将运行您的应用程序并为该目录分配适当的权限，或选择不需要提升权限访问该目录的其他文件夹。



您没有指定这是一个Web应用程序，还是指定为winforms / desktop应用程序，只能将表单视为标记。如果它是一个webforms应用程序，我强烈建议您不要让您的Web应用程序以这种方式访问​​您的本地目录，它会成为一个安全问题。

So your problem is your application doesn't have proper permissions to access c:\users\inconnu\documents\ma music. Your first screenshot only shows the shortcut to your documents folder (which doesn't help much).

Your solution here is to either run your code with administrator privileges, figure out what user is going to run your app and assign proper permissions to the directory, or choose a different folder that doesn't require elevated permissions to access that directory.

You don't specify if this is a web app or if it as winforms/desktop app, only see "forms" as a tag. If it is a webforms app i would highly recommend you don't allow your web application access to your local directories in this manner, it becomes a security issue among other things.
