什么是脱字符（“^”）在C ++ / CLI是什么意思？ [英] What does the caret (‘^’) mean in C++/CLI?

问题描述

我刚刚碰到这个code和一些谷歌搜索打开了这个神秘的（对我）的语法没有解释。

I just came across this code and a few Google searches turn up no explanation of this mysterious (to me) syntax.

Hashtable^ tempHash = gcnew Hashtable(iterators_);

IDictionaryEnumerator^ enumerator = tempHash->GetEnumerator();

什么鬼不插入符号是什么意思？ （该 gcnew 也是新的给我，我问有关的这里。）

What the heck does the caret mean? (The gcnew is also new to me, and I asked about that here.)

推荐答案

这是 C ++ / CLI ，并插入符是*（指针）的管理相当于这在C ++ / CLI术语中被称为的句柄以一个引用类型（因为你仍然可以有非托管指针）。

This is C++/CLI and the caret is the managed equivalent of a * (pointer) which in C++/CLI terminology is called a 'handle' to a 'reference type' (since you can still have unmanaged pointers).
