读取配置文件在另一台计算机上不起作用

Question

我正在 C# 中制作 Windows 应用程序。我在 .NET Framework 3.5 中制作了一个应用程序，并且使用的是 Windows Vista。当我构建该应用程序并尝试在另一台装有 Windows 7 的计算机上运行时，它不起作用。目标计算机在控制面板中显示 .NET Framework 4.0 客户端配置文件。每当我尝试从配置文件中读取某些值时，就会出现此问题。如果我不使用配置文件，那么我的应用程序会运行，但我必须使用配置文件。 为了检查框架问题，我制作了一个简单的应用程序，其中我尝试在单击按钮时读取配置文件值 MessageBox.Show(ConfigurationManager.AppSettings["FlagForArchiving"].ToString()); 但我收到错误，

See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

请帮助我解决我的问题。提前致谢。

Answer 1

将配置文件更改为“.NET Framework 3.5”。 “.NET Framework 3.5 客户端配置文件”有一些限制，并且不会提供您可能需要的所有程序集。

Answer 2

FileNotFoundException 表示您的应用文件夹中不存在配置文件。确保在发布应用程序时部署配置文件。

是的，您需要在安装应用程序的每台计算机上都有一个配置文件。

Answer 3

可能是因为目录访问。通过管理员运行您的应用程序以保证访问。
