问题：运行我的应用程序时使用Windows 7，未经授权的访问异常 [英] Question: Using Windows 7, Unauthorized Access Exception when running my application

问题描述

我的应用程序正在引发未经授权的访问错误。在运行我的应用程序时，我尝试访问以下位置的目录：Application.UserAppDataPath。

My application is raising an unauthorized access error. While running my application, I try to access a directory in the following location: Application.UserAppDataPath.

问题：它说我没有访问应用程序的权限。 UserAppDataPath目录

The Problem: It says I do not have permission to access the Application.UserAppDataPath directory

有没有办法在我的应用程序源代码中设置权限？

Is there a way to set permissions within my application source code?

如下所示：

Application.UserAppDataPath.SetPermissions()

推荐答案

看着你的评论，你说这是你的代码：

Looking at your comment, you say this is your code:

StreamReader sr = new StreamReader(Application.UserAppDataPath);

Application.UserAppDataPath 是一个目录，而不是文件。如果您尝试直接打开它，就像尝试打开一个文件下面的文件一样，AppData文件夹，您真的没有权限。

Application.UserAppDataPath is a directory, not a file. If you try to open that directly, it's the same as trying to open a file one level below the AppData folder, which you really don't have permission to do.

使用 Path.Combine 构建AppData文件夹内的文件的路径，即

Use Path.Combine to construct a path to a file inside the AppData folder, i.e.

string fileName = Path.Combine(Application.UserAppDataPath, "settings.xml");
StreamReader sr = new StreamReader(fileName);

当然这只是一个例子 - 实际上你应该在AppData中使用一个子文件夹特定于您的应用程序。

Of course this is just an example - in reality you should probably be using a sub-folder inside AppData specific to your application.
