在C＃类库中使用IConfiguration [英] Using IConfiguration in C# Class Library

问题描述

我正在使用C＃和Core .NET构建类库。我正在尝试使用 config.json 文件中的配置。该文件的内容如下：

I am building a class library using C# and Core .NET. I am trying to use configuration from a config.json file. Here are the contents of that file:

config.json

{
  "emailAddress":"[e-mail]"
}

在尝试使用 config.json 进行配置时，我引用的是 Microsoft.Framework.ConfigurationModel.Json 在我的 project.json 文件中。在我的代码中，我有以下内容：

In an attempt to use config.json for my configuration, I'm referencing Microsoft.Framework.ConfigurationModel.Json in my project.json file. In my code, I have the following:

MyClass.cs

using Microsoft.Framework.ConfigurationModel;
public class MyClass
{
  public string GetEmailAddress()
  {
//    return ConfigurationManager.AppSettings["emailAddress"];  This is the approach I had been using since .NET 2.0
    return ?;  // What goes here?
  }
}

自.NET 2.0起，我一直在使用 ConfigurationManager.AppSettings [ emailAddress] 。但是，我现在正在尝试通过 IConfiguration 来学习新方法。我的问题是，这是一个类库。因此，我不确定如何，何时何地加载配置文件。在传统的.NET中，我只需要为ASP.NET项目命名一个文件web.config，为其他项目命名一个app.config。现在，我不确定。我同时拥有一个ASP.NET MVC 6项目和一个XUnit项目。因此，我试图弄清楚如何在这两种情况下使用 config.json 。

Since .NET 2.0, I had been using ConfigurationManager.AppSettings["emailAddress"]. However, I'm now trying to learn how to do it the new way via IConfiguration. My problem is, this is a class library. For that reason, I'm not sure how, or where, or when, the configuration file gets loaded. In traditional .NET, I just needed to name a file web.config for ASP.NET projects and app.config for other projects. Now, I'm not sure. I have both an ASP.NET MVC 6 project and an XUnit project. So, I'm trying to figure out how to use config.json in both of these scenarios.

谢谢您！

推荐答案

从未使用过，但快速搜索将其引导至此...

Never used it but a quick search lead me to this...

var configuration = new Configuration();
configuration.AddJsonFile("config.json");
var emailAddress = configuration.Get("emailAddress");

也许您可以尝试。
