// See https://aka.ms/new-console-template for more information using System.Dynamic; /*个人理解  * ExpandoObject和匿名对象区别  * ExpandoObject 可变，匿名对象定好后不能变  *  * dynamic和var 区别 参考链接https://www.cnblogs.com/yayazi/p/8998610.html  * dynamic运行时解析，var编译后匹配实际类型  * 也可以说var比dynamic早  */   var result = new ExpandoObject();//var解析为实际类型 dynamic result2 = new ExpandoObject();//dynamic运行时解析，解析为Object result2.Name = "张三"; //result.Name = "张三";//报错 Console.WriteLine(result2.Name);   var result3 = new {Name="李四",Age=15 }; //result3.Address = "湖南";//报错 Console.WriteLine(result3.Name); Console.WriteLine(result3.Age);
