讀取配置文件,appsettings.json和注入ICO

https://www.cnblogs.com/knowledgesea/p/7079880.html

引入Nuget的兩個類庫

Microsoft.Extensions.Configuration
Microsoft.Extensions.Configuration.Json

使用

var builder = new ConfigurationBuilder().SetBasePath(Directory.GetCurrentDirectory()).AddJsonFile("appsettings.json");
var configurationRoot = builder.Build();
var motherNameSection = configurationRoot.GetSection("mother").GetSection("name");

 -------------------------------------------------------------------------------------------------------------------------------------------------------

如果我們要讀取Bin的Value值，這樣處於多層嵌套的json

 

 

只要在StartUp中加上這個-----》層級關系用"   :   "英文冒號隔開就是了

//注冊appsetting的值
services.Configure<AppSetting>(_configuration.GetSection("Zhu:Kai"));
