如何使+操作员的工作量，同时增加两分彼此？ [英] How to make the + operator work while adding two Points to each other?

问题描述

有没有办法让 + 运营工作，为Point对象？

Is there any way to get the + operator to work for the Point object?

举个例子来说，这个小片段：

Take, for example, this tiny snippet:

this.cm1.Show((MouseEventArgs)e.Location+this.i_rendered.Location);

您看，我尽量补充两点海誓山盟。它只是不工作（这是预期）。我很想得到这个工作。

You see, I try to add two points to eachother. It just does not work (which was expected). I'd love to get this working.

任何想法？

推荐答案

这不会发生，你期望的方式。唯一的过载，该点结构提供了 + （加）运算符的one是翻译的点由<$ C坐标$ C>尺寸 。

It's not going to happen the way you expect. The only overload that the Point structure provides for the + (addition) operator is one that translates the coordinates of the Point by a Size.

有没有办法将两个点结构在一起，我甚至不知道这意味着什么。

There's no way to add two Point structures together, and I'm not even sure what that would mean.

不要浪费太多时间想出来的，或者说，考虑到<一href="http://stackoverflow.com/questions/172658/operator-overloading-with-c-sharp-extension-methods">you不能写超负荷运营商的扩展方法。

Don't waste too much time figuring it out, either, considering that you cannot write extension methods that overload operators.

幸运的是，在编译语言，没有处罚分手了code成多行。所以，你可以重新写你的code如下：

Fortunately, in a compiled language, there's no penalty for splitting up code into multiple lines. So you can re-write your code as follows:

Point newLocation = new Point(e.Location.X + this.i_rendered.Location.X,
                              e.Location.Y + this.i_rendered.Location.Y);
this.cm1.Show(newLocation);

另外，您也可以使用 偏移方法，但我不认为这增强了可读性。

Alternatively, you could use the Offset method, but I'm not convinced that enhances readability.
