在c#中，`new object()`和`new {}`之间有什么区别吗? [英] Is there any difference between `new object()` and `new {}` in c#?

问题描述

在c#中，

var x = new {};

声明一个没有属性的匿名类型.这和

declares an anonymous type with no properties. Is this any different from

var x = new object();

?

推荐答案

是的，使用的类型不同.您可以在编译时告诉这一点:

Yes, the types used are different. You can tell this at compile-time:

var x = new {};
// Won't compile - no implicit conversion from object to the anonymous type
x = new object(); 

如果您要问new{}是否有用过 -那是另一回事...我无法立即想到它的任何合理用途.

If you're asking whether new{} is ever useful - well, that's a different matter... I can't immediately think of any sensible uses for it.
