我正在用 c# 制作 windows 应用程序。我在 .NET framework 3.5 中制作了一个应用程序，我正在使用 windows vista。当我构建该应用程序并尝试在其他具有 windows 7 的机器上运行时，它无法正常工作。目标机器在控制面板中显示 .NET 框架 4.0 客户端配置文件。每当我尝试从 CONFIG 文件中读取一些值时，就会出现此问题。如果我不使用配置文件，那么我的应用程序将运行，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，在该应用程序中，我尝试在单击按钮时读取配置文件值， MessageBox.Show(ConfigurationManager.AppSettings["FlagForArchiving"].ToString()); 但出现错误

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.

请帮我解决我的问题。在此先感谢。

FileNotFoundException意味着配置文件不存在于您的应用程序文件夹中。确保在发布应用程序时部署了配置文件。

是的，您需要在安装了您的应用程序的每台机器上都有一个配置文件。

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。

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