在程序的数据段中分配什么类型的变量? [英] What type of variables are allocated in data segment of a program?

问题描述

请在程序的数据段中列出，声明了什么类型的变量/具有内存?

In data segment of a program, please list,what type of variables are declared/have memory?

推荐答案

类和结构的所有静态字段.如果它们是引用类型，则引用存储在数据段中，而对象本身存储在堆中.

使用C ++/CLI，情况更加复杂.这种语言是唯一的，因为它甚至允许引用类型实现值语义.并且显式声明了托管引用("^").因此，即使引用类型的静态对象也可以存储在数据段中.仅当对引用类型的对象的引用表示静态字段时，该引用才存储在数据段中，而对象本身存储在堆中.

通常，如果使用gcnew(对于C#为new)，则引用类型对象存储在堆中.

All static fields of classes and structures. If they are of a reference type, the reference is stored in data segment, and the object itself — in the heap.

With C++/CLI, the situation is more complex. This language is unique as it allows for value semantic even for reference types; and the managed references are declared explicitly (''^''). So even the static object of reference type can be stored in the data segment. Only if a static field is represented by the reference to the object of reference type, the reference is stored in the data segment and the object itself in the heap.

Generally, reference-type objects are stored in the heap if gcnew (new for C#) is used.
