新建一个控制台应用，添加两个Package：
Install-Package Microsoft.Extensions.Configuration Install-Package Microsoft.Extensions.Configuration.Json
创建配置文件appsettings.json：
{
"Data": "10000",
"ConnectionStrings": {
"DevContext": "开发库",
"ProdContext": "生产库"
}
}
读取配置文件：
using System; using System.IO; using Microsoft.Extensions.Configuration; namespace Libing.Core.ConsoleApp { class Program { static void Main(string[] args) { var builder = new ConfigurationBuilder() .SetBasePath(Directory.GetCurrentDirectory()) .AddJsonFile("appsettings.json"); var config = builder.Build(); Console.WriteLine(config["Data"]); Console.WriteLine(config.GetSection("ConnectionStrings:DevContext").Value); } } }
通过ConfigurationBuilder对象来创建ConfigurationRoot对象，进行读取配置文件。
SetBasePath：设置配置文件基础路径
AddJsonFile：添加读取的Json文件
