c ++ caret ^ Vs.指针*？ [英] c++ caret^ Vs. Pointer*?

问题描述

我已经编程了很长时间在C和C＃，我认为移动到C ++将是流畅的...

反正，我已经看到使用插入符号，但我不

  
 std :: string * st1; 
  

到

  String :: string ^ st2; 
  

$ b

谢谢！

解决方案

插入符号特定于 C ++ / CLI ，Microsoft的.NET版本C ++，其中托管的等效指针。

它实际上不是标准C ++的一部分，所以除非你真的要使用.NET，否则不要使用。

I've programming for a long time in C and in C#, I thought moving to C++ would be smooth...
anyway, I've seen the use of caret but I don't understand the meaning of it.

what's the different between:

std::string *st1;

to

String::string ^st2;

Thanks!

解决方案

The caret is specific to C++/CLI, Microsoft's .NET version of C++, where it is the managed equivalent of a pointer.

It is not actually part of standard C++, so unless you truly mean to use .NET, don't use it.
