使用类库从 web.config/app.config 获取配置设置 [英] Getting configuration settings from web.config/app.config using class library

问题描述

3.5 中的配置设置让我发疯...救命！;)

Configuration settings in 3.5 is driving me nuts... Help! ;)

我有一个类库(命名为 ADI)，它需要使用它的项目中的一些配置设置(如连接字符串、文件系统位置等).

I have a class library (Named ADI), that needs some configuration settings from the project using it (like connectionstring, filesystem locations etc).

我想在我的 Windows 窗体/Web 项目 App.Config 或 Web.Config 中定义这些设置，就像其他设置一样.

I want to define these settings in my Windows Forms/Web Projects App.Config or Web.Config, like other settings.

这是我的 windows 窗体应用程序的 app.config 的一部分:

Here is part of my app.config for my windows forms application:

<applicationSettings>
    <PhotoImportRobot.My.MySettings>
      <setting name="ADIImageRoot" serializeAs="String">
        <value>C:DataTempADIOriginal</value>
      </setting>
      <setting name="ADIImageVariantsRoot" serializeAs="String">
        <value>C:DataTempADIVariants</value>
      </setting>
    </PhotoImportRobot.My.MySettings>
</applicationSettings>

我如何从我的类库中访问它??

How do I access that from my class library??

我试过了:

System.Configuration.ConfigurationManager.AppSettings("ADIImageVariantsRoot")

怎么办?

推荐答案

如果你不追求结构化设置，appSettings 部分只需要键值对:

If you're not after structured settings, the appSettings section just takes key-value pairs:

<appSettings>
  <add key="ADIImageRoot" value="C:DataTempADIOriginal" />
  <add key="ADIImageVariantsRoot" value="C:DataTempADIVariants" />
</appSettings>

这将使您能够通过 AppSettings 字典访问它们:

This will enable you to access them via the AppSettings dictionary:

ConfigurationManager.AppSettings["ADIImageVariantsRoot"]

如您所料.

或者，如果您需要更多的配置结构(即不仅仅是字符串或一组设置)，您可以考虑使用自己的配置部分，使用 ConfigurationSection 及其相关部分.

Alternatively, if you need more structure to your configuration (i.e. more than just strings, or a collection of settings), you can look into using a configuration section of your own, using a ConfigurationSection, and its relevant parts.
