定义硬编码值的最佳位置在哪里？ [英] Where is best place to define hard coded values?

问题描述

如果我有许多硬编码值，例如文件路径，文件名，超时，

等，哪里是定义它们的最佳位置？意思是，例如，某些东西需要更改，而不是运行可能包含这些值的所有子函数或

函数，我想要一个地方更改它们

并将更改反映在使用那些

值的子函数或函数中。我想避免使用全局变量;保持价值仅对那些使用它们的人来说是私有的。


谢谢，

Brett

解决方案

我会创建一个对类或表单私有的变量。

这样所有子例程和函数都可以使用它。它不会在表格或类别之外可以访问。

将混合使用一些共享变量。意思是，我将在一个类中定义

变量，这些变量也将在其他类或表单中使用。 />
对于那些共享变量，我应该创建一个只包含

的类吗？这提供了一个更改它们的位置，并通过使用它们的表单/类将这些更改级联为

。

If I have many hard coded values such as file paths, file names, timeouts,
etc, where is the best place to define them? Meaning, in the case something
needs changing for example, rather than running down all the subs or
functions that may contain these values, I''d like one place to change them
and have that changed reflected in the subs or functions that use those
values. I''d like to avoid globals; keeping the values private to only those
subs or functions using them.

Thanks,
Brett

Hi,

I would make a variable that is private to the class or form.
That way all the sub routines and functions can use it. It wont be
accessable out side the form or class.

There will be some shared variables mixed in. Meaning, I''ll define
variables in one class that will also be used in other classes or forms.
For those shared variables, should I just create a class that only houses
them? This provides one place to change them and have those changes cascade
through out forms/classes that are using them.
