推荐答案

你得到了一个当某些东西进入无限函数调用循环时堆栈溢出，就像这样

You get a stack overflow when something gets into an infinite function call loop, like this

public void MethodA()
{
    MethodA();
}

在上面的MethodA中调用自身，每次发生这种情况时都会在堆栈上保留空间但堆栈是有限的所以最终它会自动调用堆栈空间很多次。



在你的代码中Cummulative调用PreviousBalance调用Cummulative所以如果你尝试访问PreviousBalance你最终在一个无限的调用循环中。

In the above MethodA calls itself and every time this happens it reserves space on the stack but the stack is finite so eventually it calls itself so many times the stack runs out of space.

In your code Cummulative calls PreviousBalance which calls Cummulative so if you try and access PreviousBalance you end up in an infinite call loop.
