C++/CLI 中的插入符号(‘^’)是什么意思? [英] What does the caret (‘^’) mean in C++/CLI?

问题描述

我刚刚遇到了这段代码，在谷歌搜索中没有找到对这种神秘的(对我来说)语法的解释.

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();

插入符号到底是什么意思?(gcnew 对我来说也是新的，我在这里询问了这个问题.)

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

推荐答案

This is C++/CLI 和插入符号是 *(指针)的托管等效项，在 C++/CLI 术语中称为 'handle' 到'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).
