在 C# 类库中使用 IConfiguration

问题描述

我正在使用 C# 和 Core .NET 构建一个类库.我正在尝试使用 config.json 文件中的配置.以下是该文件的内容:

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":"[email protected]"
}

为了将 config.json 用于我的配置，我在我的 project.json 中引用了 Microsoft.Framework.ConfigurationModel.Json代码>文件.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?
  }
}

从 .NET 2.0 开始，我一直在使用 ConfigurationManager.AppSettings["emailAddress"].但是，我现在正在尝试通过 IConfiguration 以新的方式学习如何做到这一点.我的问题是，这是一个类库.出于这个原因，我不确定配置文件是如何、在何处或何时加载的.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 文件.现在，我不确定.我有一个 ASP.NET MVC 6 项目和一个 XUnit 项目.所以，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！

推荐答案

从未使用过它，但快速搜索使我找到了这个...

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

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

也许你可以试试.
