应用程序配置修改未反映在代码中 [英] App Config Modification not reflected in code

问题描述

我在 appconfig 文件中有一个 appsetting 部分

I have a appsetting section in appconfig file as

<appSettings>    
  <add key="DayTime" value="08-20"/>
  <add key="NightTime" value="20-08"/>
</appSettings>

我很想在应用程序运行时修改应用程序配置.我在应用程序运行时将键 DayTime 更改为 11-20.

I am tyring to modify the app config while application is running. I changed key DayTime to 11-20 while application is running.

现在，如果我再次运行此代码以从配置中获取数据，它会显示之前的设置值.

Now if I run this code again to fetch data from config, it shows previous set values.

private void btnDayNightSettings_ShowingEditor(object sender, ItemCancelEventArgs e)
{
     string[] strDayTime = ConfigurationManager.AppSettings["DayTime"].Split('-');
}

为什么会这样?

推荐答案

app.config 文件中的 AppSetting section 在更新过程中没有得到反映的原因运行时间如下:

The reason behind why the AppSetting section in app.config file is not getting reflected during update in Run time is as follows:

• 当您添加新的 app.config 文件时，它实际上会在本地系统中创建一个文件.
• 当你编译它时，它实际上会在Debug/Release文件夹中创建必要的文件，包括.Exe文件；取决于构建模式.
• 成功构建后，它还会生成一个 .config 文件，它看起来像 YourApplicationName.exe.config，其中包含原始 app.config 文件中的相同条目.而 .Exe 总是指向这个文件.
• 因此，每当您在运行时编辑 app.config 时，它实际上都会更新文件，但是 YourApplicationName.exe.config 文件中的更改不会更新，因为它没有重新尚未构建.

• When you add a new app.config file it actually creates a file in the local system.
• When you compile it, actually it creates the necessary files including .Exe files in Debug/Release folder; depending upon the Build mode.
• After successful build it also generates a .config file which looks like YourApplicationName.exe.config which holds the same entries in original app.config file. And the .Exe always refers to this file.
• So whenever you edit the app.config at Runtime it actually updates the file but changes are not updated in YourApplicationName.exe.config file as it has not re-build yet.

因此，每次您需要重新构建应用以反映更改时.

So every time you need to re-build to your app to reflect the changes.
