如何知道一个函数是属于.NET还是C ++？

Question

我目前在Visual Studio上使用.NET C ++。

我知道.NET和C ++之间的区别：在这种情况下，C ++是一种编程语言，.NET是基于C ++的框架。如果我错了，请纠正我。

但有时我会在这里问一些问题，用户问我是不是在谈论.NET函数或C ++函数。我认为某些C ++的函数被.NET覆盖，但我不清楚如何区分一个函数是否属于C ++或.NET。

也许这是一个非常简单的问题，但我对此并不确定。

Read the docs as a first step (and usually the last). In visual studio, at least, you can just hit F1 to bring that up in a browser. That said, if the function takes or returns any managed references (eg. ones with a ^) or if the class must be allocated with gcnew it is .net.

Regarding the specific issue from your last question (it was slightly whether an array<> was managed or unmanaged), the major issue was simply that your question lacked the C++-CLI tag, so the answerers were not immediately aware of the language you were using and assumed C++, as you did have that tag.

The specific issue of array is partially because you can use it in C++-CLI without having to add a using namespace or a cli:: namespace qualification. Thankfully, the cli namespace only contains 4 things and is the only one to be imported implicitly into a C++-CLI project. Everything else in .net is part of a managed namespace (I believe), and it should be obvious which bits of functionality you're pulling in from those.

...并且用户问我是否在谈论.NET功能或C ++功能。

我想在这种情况下用户想知道的是你是在谈论托管类还是C ++ / CLI实现中的非托管类。实际上，您可以在C ++ / CLI中声明两种类型：托管类型，声明为＆＃34; ref class＆＃34; （有时也称为包装类），或简单的本机非托管类型，简称为＆＃34; class＆＃34;。

主要区别在于你可以在＆＃34; ref class＆＃34;中使用所有.NET类，而普通＆＃34;类＆＃34;就像一个普通的C ++类。而且，＆＃34; ref class＆＃34;有很多语法扩展需要连接.NET框架，本地＆＃34;类＆＃34;缺乏。
