从config.json使用services.Configure配置属性 [英] Configuring properties from config.json using services.Configure

问题描述

从StackOverflow的问题就在 mvc6使用IConfiguration href=\"http://stackoverflow.com/questions/27179370/using-iconfiguration-globally-in-mvc6\">全球范围内继。以接受的答案注释建议使用

Following on from a StackOverflow question regarding Using IConfiguration globally in mvc6. A comment to the accepted answer suggests using

services.Configure<SomeOptions>(Configuration);

现在能正常工作有以下code;

Now this works fine with the following code;

类

public class SomeOptions
{
    public string MyOption { get; set; }
}

config.json

{
    "MyOption": "OptionValue"
}

Startup.cs

public Startup(IHostingEnvironment env)
{
    Configuration = new Configuration()
        .AddJsonFile("config.json")
        .AddEnvironmentVariables();
}

public void ConfigureServices(IServiceCollection services)
{        
    services.Configure<SomeOptions>(Configuration);
}

然而， config.json 文件没有任何真正的结构，我想它看起来更像;

However the config.json file doesn't have any really structure, and I would like it to look more like;

{
    "SomeOptions": {
        "MyOption": "OptionValue"
    }
}

然而，这不结合的类内的值。反正是有允许这样做？

However this does not bind the values within the class. Is there anyway to allow this?

推荐答案

如果你想修改 config.json 结构也需要改变您的类结构

If you want to change the config.json structure you also need to change your class structure.

{
    "SomeOptions": {
        "MyOption": "OptionValue"
    }
}

映射到像

public class SomeOptions
{
    public List<MyOption> MyOptions { get; set; }
}

public class MyOption
{
    public string OptionValue { get; set; }
}
