一旦运行，App.config不会“刷新”？ [英] App.config doesn't 'refresh' once runned?

问题描述

我有运行的Windows服务（用VB.NET制作），并希望能够不时更改
一些参数通过在App.config中更改它们。

但似乎应用程序没有使用

App.config中的更改值，但继续使用启动期间的值。


有没有办法让应用程序使用App.config中的新值？

是我应该运行哪种刷新功能？或者我应该以另一种方式做这个吗？


谢谢，


彼得

Hi,

I have a Windows Service running (made in VB.NET), and wanted to be able to
change from time to time some parameters by changing them in the App.config.
But it seems that the application doesn''t use the changed values in the
App.config, but continue to use the values that were there during start-up.

Is there a way to let the application use the new values in the App.config?
Is there kind of some ''refresh'' function that I should run? Or should I do
this on an other way?

Thanks,

Pieter

推荐答案

我可能错了，但是IIRC app.config是编译过程的一部分，所以我认为它很可能是你必须重新编译项目，除非你在运行时专门设置它以查看该文件（或者知道它应该是
）。

I might be wrong but IIRC the app.config is part of the compile process, so I
think it''s likely that you would have to recompile the project, unless you
specifically set it to look in that file during runtime (or know that it''s
supposed to).

那不是真的。 App.Config被复制到exename.exe.config。然后在运行时阅读

而无需任何重新编译。

That''s not true. App.Config is copied to exename.exe.config. It is then read
at runtime without needing any recompilation.

在编译期间（或之后），app.config文件只是复制到

目标目录并重命名为< your_app_name> .exe的.config。然后在应用程序启动时阅读

。


我不知道有任何重新加载配置的方法。该文件包含了无法重新加载的应用程序启动所需的信息（如运行时

依赖关系等）。


如果你需要在运行时更改参数，我建议您使用

注册表或一些SQL数据库作为参数或使用另一个

配置文件（说app.xml）和FileSystemWathcher等，但我猜

这太复杂了。


HTH，

During (or after) compilation, the app.config file is just copied to the
target directory and renamed to <your_app_name>.exe.config. It''s then read
on application startup.

I''m not aware of any way of reloading the configuration. The file contains
information that''s required for application startup (like runtime
dependencies, etc.) which could not be reloaded.

If you need to change parameters during runtime, I suggest you either use
the registry or an some SQL database for your parameters OR use another
configuration file (say app.xml) and a FileSystemWathcher etc., but I guess
that would be way too complicated.
