从类库项目中的 App.config 读取 [英] Read from App.config in a Class Library project

问题描述

我正在开发一个简单的类库项目，它会给我一个 dll.

I am developing a simple class library project, which will give me a dll.

我想从配置文件中读取一个特定的值.所以我在我的项目中添加了一个 App.config 文件.

I wanted a particular value to be read from a config file. So I have added an App.config file to my project.

 <?xml version="1.0" encoding="utf-8" ?>
 <configuration>

  <appSettings>
  <add key="serviceUrl" value="test value" />
  </appSettings>

  </configuration>

以上是我的 App.config 文件，现在我正在尝试按照以下方式阅读它

Above is my App.config file, and now I am trying to read it as following

  string strVal = System.Configuration.ConfigurationManager.AppSettings["serviceUrl"];

但是我的字符串变量没有得到任何值.

But I am not getting any value in my string variable.

我以类似的方式为 Web 应用程序完成了此操作，并且奏效了.但不知何故，我无法让它发挥作用.

I had done this for a web application in a similar way and it worked. But somehow I am not able to get this working.

首先将 App.config 放在类库项目中的想法是否正确?

Is the idea of having App.config in a class library project correct in the first place ?

推荐答案

如我的评论中所述，将 App.Config 文件添加到主解决方案中，而不是在类库项目中.

As stated in my comment, add the App.Config file to the main solution and not in the class library project.
