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>() });
