如何在新的C ++ / CLI语法中执行__typeof（__ box MyValueType）？ [英] How do I do __typeof(__box MyValueType) in the new C++/CLI syntax ?
问题描述
推荐答案
嗨伯尔尼，
Hi Bern,
>我该如何做__typeof （__box MyValueType）在新的C ++ / CLI语法中？
>How do I do __typeof(__box MyValueType) in the new C++/CLI syntax ?
由于新的C ++ / CLI没有使用__box关键字来进行拳击，我是害怕b / b
似乎不存在一对一翻译，我的想法是
以下：
（（MyValueType ^）MyValueTypeVar） - > GetType（）
谢谢！
祝你好运，

Since the new C++/CLI doesn''t use the __box keyword to do the boxing, I am
afraid there seems not existed an one to one translation, my idea is as the
following:
((MyValueType^)MyValueTypeVar)->GetType()
Thanks!

由于新的C ++ / CLI没有使用__box关键字来进行拳击，我是害怕b / b
似乎不存在一对一翻译，我的想法如下：
（（MyValueType ^）MyValueTypeVar） - > GetType（）
Since the new C++/CLI doesn''t use the __box keyword to do the boxing, I am
afraid there seems not existed an one to one translation, my idea is as the
following:
((MyValueType^)MyValueTypeVar)->GetType()
" - > GetType（）"和__ typeof是
" - > GetType（）"需要一个对象的实例，而__ typeof需要一个对象的实例。没有。
因此相当于__ typeof在C ++ / CLI中是:: typeid。
请参阅：typeof转到T :: typeid

The difference between "->GetType()" and "__typeof" is that
"->GetType()" requires an instance of an object while "__typeof" does not.
Therefor the equivalent of "__typeof" in C++/CLI is "::typeid".
See: typeof Goes to T::typeid
http://msdn2.microsoft.com/en-us/lib...60(VS.80).aspx

感谢您的建议， Jochen。
所以等价的表达式可能是：
MyValueType :: typeid

Thanks for the suggestion, Jochen.
So the equivalent expression could be:
MyValueType::typeid
