因为obj对象是Object类型。 先将上文中的GetAnonymousObj函数改造成返回dynamic 类型:private static dynami 5、c GetAnonymousObj() dynamic anonymousObj = new UserName = "admin", Password = "1111" return anonymousObj; 接着调用GetAnonymou

var 与new 关键字一起使用时,可以创建匿名类型。 12. /// </summary> 13. class 14. { 15. static void Main(string[] args) 16. { 17. new { name = "it小金", age = 24 };//匿名类型只是一个继承了Object 的、没有名称的类。该类的定义从初始化器中推断,类似于隐式类型化的变量。 18. ...
C# 3.0’s Anonymous Type is a cool feature and it allows us to create object and collection of no type. Actually the type does not exist but on the fly you can create object out of that type. Let’s say you need to create some object which will have two properties Id of type int ...
