c# - 什么术语用于描述两个类何时相互依赖？

Question

我在 C# 中有以下两个类:

public class MyFirstClass : IMyFirstClass
{
    MySecondClass mySecondClass;
    public MyFirstClass(IMySecondClass mySecondClass)
    {
        this.mySecondClass = mySecondClass;
    }

    public MyFirstClass() : this(new MySecondClass()){}
}

public class MySecondClass : IMySecondClass
{
    MyFirstClass myFirstClass;
    public MySecondClass(IMyFirstClass myFirstClass)
    {
        this.myFirstClass = myFirstClass;
    }

    public MySecondClass() : this(new MyFirstClass()){}
}

您会注意到，当这些类中的任何一个的默认构造函数被实例化时，系统将会崩溃，因为需要进行无限次实例化。

是否有官方术语用于描述此问题？

Answer 1

这被称为 circular reference :

A circular reference, sometimes referred to as a run-around, is a series of references where the last object references the first, thus causing the whole series of references to be unusable.
