很多IF或elses [英] lots of IF or elses

问题描述

我有一个类，它有10个属性，每个属性需要根据5种不同的验证规则进行验证。我最终写了很多

IF和elses声明使我的代码变得如此丑陋。有没有更好的方式

而不是顺序IF和elses？


非常感谢

解决方案

在您描述的情况下，可能不是。它可能很难看，但如果它有效，我就不用担心它了！如果你使用了一个好的if - elseif等逻辑

模式。

switch语句可能非常适合这项任务。

非常感谢

你可以写一个函数来做所有的验证。

你可以学习这门语言的最好方法是阅读一些关于它的书。


干杯，

I have a class which it has 10 properties, and each property needs to be
validated against 5 different validation rules.I ended up writing a lot of
IF and elses statement which has made my code so ugly.Is there a better way
to do instead of sequential IF and elses?

Thanks a lot

解决方案

In the case you describe, probably not. It may be ugly, but if it works, I
wouldn''t worry about it! Provided you''ve used a good if - elseif etc. logic
pattern.

The switch statement may be perfect for this task.

You can write a function to do all the validations.
Best way you can learn the language is to read a few books about it.
