如果在构造函数中引发异常会发生什么 [英] What happens if an exception is raised in constructor

问题描述

可能重复：

如果我在一个派生类的构造函数中抛出一个异常，是调用去清除基类的析构函数吗？

If I throw an exception in the constructor of a derived class, is the destructor called to clean up the base class?

推荐答案

然后以相反的顺序调用基类的析构函数。

The destructors of the base class(es) are then called in the reverse order.

在此之前，任何已经初始化的成员的析构函数也将被调用。

Before that, the destructors of any already initialized member will also get called.

然而，当前构造的派生类的析构函数不会被调用，因为对象的这部分将不会真正构造。

However, the destructor of the currently constructed derived-class won't get called, as this part of the object will not have been really constructed yet.
