ASP.NET 5 讀取設定檔

以往舊的Web.config不見了，要用以下方式 新增ASP.NET 組態檔






文件內容 

{
 "Data": {
  "DefaultConnection": {
   "ConnectionString": "Server=(localdb)\\MSSQLLocalDB;Database=_CHANGE_ME;Trusted_Connection=True;"
  }
 }
}

讀取方式

var builder = new ConfigurationBuilder();
builder.AddJsonFile("config.json");           
var config = builder.Build();
            
string connStr = config.GetSection("Data:DefaultConnection:ConnectionString").Value;
