File Access Permission的意思|示意

Access denied. You do not have permission to access this file.

拒绝访问。您没有访问此文件的权限。

Sometimes your partially trusted code simply needs access to the file system without prompting the user for permission.

有时您的半信任代码仅仅需要在不提示用户需求权限的情况下访问文件系统。

You cannot access the file, except when you have got the permission from the supervisor.

除非你已从上司取得批准，你不可以存取档案。

For example, the file permission constructor could create an object representing either no access to any files or all access to all files.

例如，文件权限构造函数可以创建一个对象，该对象表示不能对任何文件进行任何访问或可对全部文件进行所有访问。

Another major problem is that attempting to access each file to determine user access permission can result in a lot of failed accesses.

另一个主要问题是试图访问每个文件，以确定用户访问权限可能会导致大量的失败的访问。

For example, where file access requires full-trust permissions, if the application requests file-access permission, it will only be granted file-access permission, not full-trust permissions.

例如，文件访问需要完全信任权限时，如果应用程序请求文件访问权限，则它仅被授予文件访问权限，而不会被授予完全信任权限。
