继承Readonly成员 [英] Inherited Readonly Members

问题描述

我在一个标记为readonly的抽象类中有一个字段。但是，当我尝试在继承它的类的构造函数中修改该字段时，我得到一个

编译时错误，指出''readonly字段不能分配给

（除了在构造函数或变量初始化程序中）。''任何想法都是

apreciated，虽然我希望我不必使用一个属性。

Reuben。

I have a field in an abstract class marked readonly. However, when I attempt
to modify that field in the constructor of a class which inherits it, I get a
compile-time error stating that ''A readonly field cannot be assigned to
(except in a constructor or a variable initializer).'' Any ideas would be
apreciated, though I was hoping I wouldn''t have to use a property.

推荐答案

它只能在包含类的构造函数或其
变量初始值设定项。私有（非只读）字段，受保护的设置方法

也会这样做，是吗？


问候，

It can only be changed in the containing classes constructor, or in its
variable initializer. Private (non readonly) field, protected set method
would do the same, yes?

您不需要set方法，只需访问该字段直接，如果你宣布它受到保护。
