所以这有效..

public MyClass(ref Apple apple)
{
    apple = new Apple("Macintosh"); // Works fine
}

但有可能做这样的事情吗？

private Apple myApple;

public MyClass(ref Apple apple)
{
    myApple = apple;
}

public void ModifyApple()
{
    myApple = new Apple("Macintosh"); // does not change the input variable like the first example did
}

当ref变量被复制到成员变量时,myApple它似乎失去了它的'ref-ness'并且重新赋值它不再改变输入变量.有没有解决的办法？
