在 C# 中，从构造函数调用虚拟方法安全吗？
可能的重复：
构造函数中的虚拟成员调用
在C#中，调用虚拟方法是否安全来自构造函数？语言规范怎么说？请同时引用规格。通过安全，我的意思是它会调用派生类的实现吗？
我心中存在这个疑问，因为在 C++ 中，从构造函数调用虚函数是不安全的。

Virtual member call in a constructor
In C#, is it safe to call virtual method from constructor? What does the language specification say? Please quote from the spec as well. By safe, I mean would it call the implementation of the derived class?
This doubt exists in my mind, because in C++, it is not safe to call virtual function from constructor.

你可以这样做，但你不应该这样做。我认为 C# 甚至会给你一个警告。
当该函数被派生类重写时，它变得非常危险，因为您现在在调用派生类的构造函数之前调用该函数。
You can do it, but you shouldn't. I think C# even gives you a warning for it.
It becomes very dangerous when the function has been overridden by a derived class, because you're now calling into that function before the derived class's constructor has been called.
这是不安全的，因为虚函数将在匹配的构造函数有机会建立类不变量之前被调用。
相比之下，它在 C++ 中是安全的——被调用的函数是在匹配的构造函数期间调用的，而不是之前。
It's not safe, since the virtual function would be called before the matching constructor has had a chance to establish the class invariants.
In contrast, it IS safe in C++ -- the function which is called is called during the matching constructor, not before.
