ASP.NET Core 讀取配置文件JSON 數據、數組

配置訪問介面

public  IConfiguration _Config;
public 類名 (IConfiguration Config)
{
　　_Config = Config;
}

配置文件數據示例

{
    "AllowedHosts": "*",
    "Users": [
      {
        "Id": "123",
        "Username": "me"
      },
      {
        "Id": "456",
        "Username": "notme"
      }
    ]
  }

var allowedHosts=_Config["AllowedHosts"];  // * 
var allowedHosts=_Config["Users:1:Id"];  // 123
var allowedHosts=_Config["Users:2:Id"];  // 456


//獲取整個數組的所有值
var UserData = _Config.GetSection("Users");
var UserArray = UserData.AsEnumerable();

 基於Json數組創建Users模型

public class Users
{
    public string Id { get; set; }
    public string Username { get; set; }
}

List<Users> TestUsers = _Config.GetSection("Users").Get<List<Users>>();
