Rectangle.FromString（） [英] Rectangle.FromString()
问题描述
我仍然在C＃周围寻找方向，我不确定什么是可能的，而不是
可能。有没有办法做相当于
Rectangle r = new Rectangle（）;
r.FromString（anotherRectangle.ToString（））;
并假设没有，小组会建议我用FromString方法创建我自己的
Rectangle类或覆盖ToString给予
更易解析的东西，或者是什么？
谢谢，
Andrew
安德鲁，
你别无选择，只能建立自己的结构，因为你不能
派生自.NET中的结构。
当然，这意味着你不能使用矩形结构
，其中使用了常规的Rectangle结构。
我很好奇你为什么要这样做。你要求更多的东西可以解析，但是，持久化到字符串并从那个相同的字符串中获取值的方法已经存在。你想做什么？
希望这会有所帮助。

我认为在
之外实现这个功能会更好矩形结构（显然）也没有新的Rectangle。我在这里假设是
，当然，所讨论的功能受到限制
可以从外部完成相当简单的事情，比如字符串
你想要的转换。在这种情况下，我认为这将是一个更好的方法
有一个RectangleStringConverter或者介绍你自己的
不可互换的矩形替换。

I''m still finding my way round C# and am not sure what is possible and not
possible. Is there any way to do the equivalent of
Rectangle r = new Rectangle();
r.FromString(anotherRectangle.ToString());
and assuming there isn''t, would the panel recommend I create my own
Rectangle class with a FromString method or override the ToString to give
something a bit more parsable, or what?
Thanks,
Andrew
Andrew,
You have no choice but to create your own structure, since you can''t
derive from structures in .NET.
Of course, this means that you couldn''t use your rectangle structure
where the regular Rectangle structure is used.
I am curious why you want to do this. You ask for something more
parsable, and yet, the methods to persist to a string and get the values
from that very same string are already there. What are you trying to do?
Hope this helps.

I think it would be better to implement this function outside of the
Rectangle structure (obviously) and also without a new Rectangle. I''m
assuming here, of course, that the functionality in question is restricted
to fairly simple stuff that can be done from the outside, like the string
conversion you want. In that case I think it would be a better approach to
have a RectangleStringConverter or something than to introduce your own
non-interchangable Rectangle replacement.
