推荐答案

您无法从服务器端授予客户端文件夹权限。如果可以这样做，你将控制互联网上的某个人访问/删除/运行你电脑中的文件！

你可以尝试用一种客户端脚本语言但它又是依赖在浏览器设置和用户首选项上。因此，您最好将应用程序设计更改为不依赖于客户端文件夹或文件夹位置。



检查以下CP问题：

如何在asp.net中打开另存为对话框 [ ^ ]

以及教程：

从ASP.Net中的SQL Server数据库上传和下载文件 [ ^ ]

演示 [ ^ ]

请注意，在上面，是否显示文件保存对话框取决于浏览器首选项。

You can't give client side folder permission from server side. if it is can be done, you will giving control to someone in the internet to access/delete/run file in your computer!
you can try with one of client side scripting language but it is again depend on the browser settings and the user preferences. so you better change your application design to without depending on client side folder or folder location.

check below previous CP question:
