(精华)2020年10月21日 设计模式案例 .NetCore Configuration的实现思路

使用

#region Configuration使用
{
    // 1、创建ConfigurationBuilder对象
    ConfigurationBuilder configurationBuilder = new ConfigurationBuilder();
    configurationBuilder.AddJsonFile("app.json");

    // 2、构建Configuration对象
    Configuration configuration = configurationBuilder.Build();
    string value = configuration["json"];
}
#endregion
