在哪里存储应用程序数据在Windows 7和Vista [英] Where to store Application Data in Windows 7 and Vista

问题描述

我的应用程序需要，最喜欢的，存储数据。该应用程序是previously用在XP只在那里将存储在数据程序文件。现在，我们的客户迁移至Windows 7，我不得不这样升级其存储在一个新的文件夹中的数据。我选择了的ApplicationData 文件夹作为我以为我会被允许访问，而无需UAC的。

现在在某些Windows 7的机器，这是好的，但在其他人访问该文件夹失败，$ P $因为权限psumably，但与管理员运行privelidges程序工作正常。

我使用了错误的文件夹或者是这些情况异常值？在这两种情况下，究竟是什么样的东西的最佳做法？

我使用下面的C＃ SpecialFolder 来获取AppData文件夹的位置。

  System.Environment.SpecialFolder.ApplicationData
 




解决方案

System.Environment.SpecialFolder.ApplicationData 为每个用户和漫游。这听起来并不像你想要什么。你似乎想计算机范围设置等应使用 System.Environment.SpecialFolder.CommonApplicationData 。

由于 CommonApplicationData 在所有用户之间共享，默认的访问控制是有限的。默认情况下标准用户不能在此位置写。建议的做法是在安装时创建 CommonApplicationData 的子文件夹，并为其分配适当宽松的访问控制设置。

My application needs to, like most, store data. The application was previously used on XP only where it would store the data in Program Files. Now that our customers are moving to Windows 7 I had to upgrade it so that it stored the data in a new folder. I opted for the ApplicationData folder as I thought I would be allowed access without needing UAC at all.

Now on some Windows 7 machines this is fine, but on others access to the folder fails, presumably because of permissions, but when ran with Administrator privelidges the program works fine.

Am I using the wrong folder or are these cases outliers? In either case what is the best practice for this kind of thing?

I am using the following C# SpecialFolder to get the AppData folder location.

System.Environment.SpecialFolder.ApplicationData

解决方案

System.Environment.SpecialFolder.ApplicationData is per-user and roams. That doesn't sound like what you want. You appear to want machine wide settings and so should use System.Environment.SpecialFolder.CommonApplicationData.

Because CommonApplicationData is shared between all users, the default access control is limited. By default standard users cannot write in this location. The recommended practise is to create a sub-folder of CommonApplicationData at installation time and assign it suitably permissive access control settings.
