具有不同访问者的属性？ [英] Properties with different accessors?
问题描述
是否可以创建一个具有与get属性不同的可访问性的set属性
？
例如，我有一个私有字段一个基类。 Get属性应该是公开的，因此任何人都可以看到该字段的值。但是，设置
属性应该受到保护且不可覆盖（因为它会根据新值进行各种额外的计算/操作）并且只能派生
类应该能够设置一个新值。
希望有意义，
提前感谢您的帮助，

Is it possible to create a set property which has a different accessibility
than the get property?
For example, I have a private field in a base class. The Get property should
be public so that anyone can see the value of the field. However the Set
property should be protected and non-overridable (since it does various
additional calculations/actions based on the new value) and only derived
classes should be able to Set a new value.
Hope that makes sense,
Thanks in advance for any help,
Ann-Marie Ratcliffe

数字;（
我猜最好解决方法是将属性作为
hoi-polloi的只读属性，然后对派生类有一个受保护的方法，但是
似乎都是这可能是一件非常简单的事情。

PS如果有一种比我上面提到的更简洁的方式，我很乐意听到它。

Figures ;(
I guess the best work-around is to have the Property as read-only for the
hoi-polloi, and then have a protected Method for the derived classes, but it
all seems like a two''n''eight for what could be so simple.
Thanks for your quick reply,

P.S. If there is a neater way than I''ve suggested above I''d love to hear it.

是的，这很痛苦 - 坦白说，我我很惊讶它是在v1.0之前没有得到的b $ b固定的。这似乎是一件显而易见的事情......
也许有些问题我不知道。
一个只读属性和一个mutator方法，反之亦然
（私有财产，公共访问者），或者只是有两种方法
目前确实是选项。
幸运的是，不仅要求下一个版本，而且
显然也会发生这种情况:)

Yes, it''s a pain - and frankly, I''m surprised it''s one which didn''t get
fixed before v1.0. It seems such an obvious thing to want to do...
maybe there are problems with it that I''m not aware of.
Having either a readonly property and a mutator method, or vice versa
(private property, public accessor), or just having two methods are
indeed the options at the moment.
Fortunately, not only has this been requested for the next version, but
apparently it''s going to happen, too :)
