阅读在.net中的的app.config或web.config设置 [英] Reading settings from app.config or web.config in .net

问题描述

我的工作，需要能够读取设置了的web.config 或的app.config 文件（取决于该DLL是从ASP.NET Web应用程序中引用或Windows窗体应用程序）。

I'm working on a C# class library that needs to be able to read settings the web.config or app.config file (depending on whether the DLL is referenced from an ASP.NET web application or a Windows Forms application).

我发现，

ConfigurationSettings.AppSettings.Get("MySetting")

工作，但code已被标记为微软pcated德$ P $。

works, but that code has been marked as deprecated by Microsoft.

我读过，我应该使用：

ConfigurationManager.AppSettings["MySetting"]

不过， System.Configuration.ConfigurationManager 类似乎没有可以从一个C＃类库项目。

However, the System.Configuration.ConfigurationManager class doesn't seem to be available from a C# Class Library project.

有谁知道做到这一点的最好办法是？

Does anyone know what the best way to do this is?

推荐答案

您需要添加引用到 System.Configuration 的项目的引用文件夹。

您绝对应该使用 ConfigurationManager中在过时的 ConfigurationSettings 。

You should definitely be using the ConfigurationManager over the obsolete ConfigurationSettings.
