Question

我在c＃中制作Windows应用程序。我在.NET framework 3.5中创建了一个应用程序，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的计算机上运行时，它无法运行。目标机器在控制面板中显示.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，那么我的应用程序运行但我必须使用配置文件。为了检查框架问题，我做了一个简单的应用程序，我试图在按钮点击时读取配置文件值MessageBox.Show(ConfigurationManager.AppSettings["FlagForArchiving"].ToString()); 但是我收到了错误

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。谢谢。

Answer 1

FileNotFoundException表示配置文件不在您的应用文件夹中。确保在发布应用程序时部署配置文件。

是的，您需要在安装了应用的每台计算机上都有一个配置文件。

Answer 2

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。

Answer 3

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

读取配置文件在另一台计算机上不起作用
