int是值类型还是引用类型?

推荐答案

这意味着在您调用ToString时，会将int装箱(变成一个对象).

It means that the int is boxed ( turned into an object ) when you call ToString on it.

This[^] might give you some idea how google works, which is bound to help you in future. The book Inside C# is a good reference to buy, but most C# books will also cover this in detail.
