自定义配置文件:

在根目录建一个Config文件夹和config.json配置文件

{
  "Person": {
    "Name": "zhangsan2222",
    "Age": 18
  }
}

Program.cs文件:

namespace WebApplication1
{
    public class Program
    {
        public static void Main(string[] args)
        {
            CreateWebHostBuilder(args).Build().Run();
        }

        public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
            WebHost.CreateDefaultBuilder(args)
            .ConfigureAppConfiguration((c, h) =>
            {
                h.AddJsonFile($"Config/config.json",true,true);
            })
            .UseStartup<Startup>();
    }
}

　　Controller文件:

[Route("[Controller]")]
    public class OptionsController : Controller
    {
        private readonly IConfiguration _configuration;


        public OptionsController(IConfiguration configuration)
        {
            _configuration = configuration;
        }

        [HttpGet("Index")]
        public IActionResult Index()
        {
            var Name= _configuration.GetValue<String>("Person:Name");

            return View(nameof(Index),Name);
        }

　　view文件:

@model String
@{
    Layout = null;
}

<!DOCTYPE html>

<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>Index</title>
</head>
<body>
    <h1>@Model.ToString()</h1>
</body>
</html>

　　绑定到实体类:

  ////第一种绑定
            //PersonOptions option = new PersonOptions();
            ////配置文件绑定Person绑定到该PersonOptions对象上
            //Configuration.Bind("Person", option);
            ////注入
            //services.AddSingleton(option);

            ////第二种绑定
            PersonOptions option = new PersonOptions();
            Configuration.GetSection("Person").Bind(option);
            services.AddSingleton(option);

　　实体类:

 public class PersonOptions
    {
        public String Name { get; set; }

        public int Age { get; set; }
    }

　　controller:

[Route("[Controller]")]
    public class OptionsController : Controller
    {
        private readonly PersonOptions _options;

        public OptionsController(PersonOptions options)
        {
            _options = options;
        }

        [HttpGet("Index")]
        public IActionResult Index()
        {
            return View(nameof(Index), _options.Name);
        }


    }
