Posted 2020-12-03 深圳丶追

1-新建json文件， 设置json文件生成的方式

 

{
  "ClassNo": "1",
  "ClassDesc": "Asp.net core",
  "Students": [
    {
      "name": "lili",
      "age": "11"
    },
    {
      "name": "xiaofeng",
      "age": "33"
    },
    {
      "name": "xiaobao",
      "age": "66"
    }
  ]
}

　2-解析json文件

　

using System;
using Microsoft.Extensions.Configuration;

namespace jsonConfigDemo
{
    class Program
    {
        static void Main(string[] args)
        {
            var builder = new ConfigurationBuilder()
                .AddJsonFile("myclass.json");

            var config = builder.Build();

            Console.WriteLine($"ClassNo: {config["ClassNo"]}");
            //下面输出第一个
            Console.WriteLine($"name: {config["Students:0:name"]} age:{config["Students:0:age"]}");
            //下面输出第二个
            Console.WriteLine($"name: {config["Students:1:name"]} age:{config["Students:1:age"]}");
            Console.ReadLine();

        }
    }
}

结果
