问题描述
大家好，
我将一个类的引用传递给一个表单的构造函数，比如
so：public MyForm（int count，ref Area myArea）{...}
如何在构造函数之外使用myArea？我应该创建另一个
区域并将myArea分配给它（即：Area foo = myArea;）还是有一个
更好的方式？

Hello all,
I''m passing a reference to a class into the constructor of a form, like
so: public MyForm(int count, ref Area myArea) {...}
How can I use myArea outside the constructor? Should I create another
Area and assign myArea to it (ie: Area foo = myArea;) or is there a
better way?

推荐答案
不，他们不是。引用按值传递。我知道这可能比说完全解释它更容易
，但我认为它确实会对
结束造成伤害。
致OP：请参阅真的意思是，和b $ b一样，C＃做什么。

No they''re not. References are passed by value. I know it may be easier
to say this than to explain it fully, but I think it does harm in the
end.
To the OP: see http://www.pobox.com/~skeet/csharp/parameters.html for a
full discussion about what "passing by reference" really means, and
what C# does.
