dynamic的好处

dynamic 可在反射、json反序列化时使用、已达到减少代码量的效果。看代码

using System;

namespace ConsoleApp2
{
    class Program
    {
        static void Main(string[] args)
        {
            System.Type t = typeof(Person);
            var obj = Activator.CreateInstance(t, null);
            t.InvokeMember("Talk", System.Reflection.BindingFlags.InvokeMethod, null, obj, new object[] { "hell world!" });

            dynamic obj2 = Activator.CreateInstance(t, null);
            obj2.Talk("hell world!");
        }
    }

    class Person
    {
        public void Talk(string msg)
        {
            Console.WriteLine(msg);
        }
    }
}

            //发送请求
            string result = HttpUtil.HttpPost(uri, url, data, headerdata);

            Console.WriteLine("获取销售易表" + table + "数据：");
            Console.WriteLine(result);
            //数据反序列化为匿名对象
            var list = JsonConvert.DeserializeAnonymousType(result, new { records = new List<dynamic>() });
