有关用户的文件权限的问题 [英] Question about file permissions for a user

你好，

我被要求开发一个给定用户名和文件名的函数，以返回用户是否有权访问文件...

我已经在互联网上阅读了很多有关显式权限的内容，但是试图达到特定用户的水平.

IE. bool HasAccess(字符串用户名，字符串FileName){}


任何帮助都很棒.

预先感谢，

Hi there,

I have been asked to develop a function that, given a user name and a file name, to return whether the user has access to the file...

I have read a lot on the internet on explicit permissions, but was trying to get to the level of the specific user.

ie. bool HasAccess(string UserName, string FileName) {}


Any assistance would be fantastic.

Thanks in advance,

Phil.

推荐答案

好问题！

我做了一些搜索，并在此处找到了一些好东西 [

Good question!

I did a bit of searching and found some goodies here[^], but the responses there are limited. The techniques posted will get you the groups that have access, but further work will be needed to find whether a user is a member of a particular group.

Best practices in the Microsoft world include granting access to groups, not users, then to assign users to groups depending on their access needs. The security model is structured to accomodate that practice, so you''ll probably have to drill down through the model to find the solution. I think the above solution will get you through the first layer, but it''s obviously not enough.
