无法以标准用户的身份创建或写入文件 [英] Unable to Create or Write to a file as standard user

问题描述

我的应用程序在连接或断开服务器时会创建日志文件。

My application creates a log file when it connects or disconnects a server. This works well win win XP.

在Vista和Win 7中以管理员身份运行它没有问题。但是如果我在Vista中运行这个标准用户， Win7然后它无法创建日志文件，我知道这是为UAC。

There are no issues while I run it as admin in Vista and Win 7. But if I run this as a standard user in Vista or Win7 then it fails to create the log file, and I know this is for UAC.

但是如何绕过这种情况，使我的应用程序将作为管理员运行。我需要在安装我的应用程序时添加任何注册表项，以便它始终以管理员身份运行。

But how can I bypass this situation so that my app will run as admin . DO I need to add any registry entry while installing my application so that it will always run as administrator.

推荐答案

您可以添加清单，导致您的应用程序在启动时需要UAC升级，但更多的时候，应该这样做。

If you really want to, you can add a manifest that causes your application to require UAC elevation when it is launched, but more often than not that's not what you should do.

更有可能的是，你写的路径你不应该。用户模式应用程序应该只写入当前用户文件夹或 C：\Users\Public 文件夹，日志应该放在 C ：\Users \Current User Name \Application Data\您的计划名称\ 。要获取ApplicationData路径，请使用 Environment.GetFolderPath（Environment.SpecialFolder.ApplicationData）。或者，如果要让所有用户共享该文件，请使用 Environment.SpecialFolder.CommonApplicationData 。

More likely, you're writing to a path you shouldn't be. User mode applications should only write to the current users folders or the C:\Users\Public folder, and things like logs should go in C:\Users\Current User Name\Application Data\Your Program Name\. To get the ApplicationData path use Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData). Or if you want to have the file shared by all users, use Environment.SpecialFolder.CommonApplicationData.
