使用ref类来保存数据？

问题描述

我有一个ref类来保存托管C ++ DLL中的数据。



类型（Stuff :: Manager）来自第三方.NET DLL。



问题在代码块的注释中。

I have a ref class to hold data in a Managed C++ DLL.

The type (Stuff::Manager) is from a 3rd party .NET DLL.

Question is in the comment in the code block.

ref class MyDataClass
{
public: 
  static Stuff::Manager^ m_Manager;
/// ...
}

伪代码...

With pseudo-code ...

void f()
{
  Stuff::Manager^ manager = GetManager();
  MyDataClass::m_Manager = manager; // Is this a transfer of ownership or just a copy ? or will manager be destroy by the scope ?
}

void g()
{
  MyDataClass::m_Manager->DoSomething();
}

int Main()
{
  f();
  g();
}

谢谢。
