                Object Student = new

                    Id = "1",

                //Console.WriteLine(Student, Name); 
                //C#强类型语言，编译时会确定类型，object 决定了没有Id属性  
                //运行时确实有Id和Name  但是编译器不认可
            }
            {

                dynamic Student = new

                    Id = "1",

            {
                //1 var 配合匿名类型使用,会根据右侧推断出类型
                //2 var 偷懒，复杂类型的使用
