操作者+ = [英] operator+=
问题描述
有没有办法为我自己的类定义上面的运算符？我似乎只能定义每一个，除了我想要的那个（总是那样:)
我问的主要原因是事件接口使用Event + = new
EventHandler（..）语法 - 我不确定如何实现它。这是
是通过运营商完成的吗？
我使用的是C＃2.0
-
问候，Fil。
Is there any way to define the above operator for my own class? I seem to be
able to define every single one, except the one I want to (always the way :)
The main reason I ask is that the event interfaces use the "Event += new
EventHandler(..)" syntax - I am not sure how this gets implemented. Is this
done via operator+?
I am using C# 2.0

是，的当然 - 但是操作员+ =通过修改项目内联而不是创建一个新的
实例来为你提供额外的功能来提高效率
不确定你是否知道，但C ++有一个运算符+ =;你不需要用操作符+来攻击它。
问候，Fil。

Yes, of course - but the operator+= gives you additional capabilities to
improve efficiency, by modifying the item inline, rather than creating a new
instance
Not sure if you''re aware, but C++ has an operator+=; you dont need to hack
it with operator+.

Fil，
1.在c＃中，你通过重载+运算符来重载+ =。
2. + =对于事件由C＃编译器处理，并且不涉及运算符
重载。有些人可能会对此声明提出异议，但我的意思是
没有生成''op_ *''方法。

Fil,
1. In c# you overload += by overloading the + operator.
2. += for events is handled by the C# compiler and doesn''t involve operator
overloading. Some may argue with this statement, but what I mean is that
there is no ''op_*'' method generated.
