    {
        static void Main(string[] args)
        {
            var builder = new ConfigurationBuilder();
            builder.AddJsonFile("json1.json");

            var configuration = builder.Build();

            Console.WriteLine($"name：{configuration["name"]}  age：{configuration["age"]}");
