创建实用程序类? [英] Creating a Utilities Class?

问题描述

我对OOP还是很陌生，并且在使用良好的编码原则的同时，尽我最大的努力使内容严格基于类.

I'm very new to OOP and am trying my hardest to keep things strictly class based, while using good coding principles.

我现在很公平地进入我的项目，并且我想将许多通用方法放入实用程序类中.是否有创建实用程序类的最佳方法?

I'm a fair ways into my project now and I have a lot of general use methods I want to put into an utilities class. Is there a best way to create a utilities class?

public class Utilities
{
    int test;

    public Utilities()
    {
    }

    public int sum(int number1, int number2)
    {
        test = number1 + number2;
    }
    return test;
}

创建此Utilities类之后，是否仅创建一个Utilities对象并运行我选择的方法?我对这个实用程序类的想法正确吗?

After creating this Utilities class, do I just create an Utilities object, and run the methods of my choosing? Do I have this Utilities class idea correct?

推荐答案

您应将其设置为static类，如下所示:

You should make it a static class, like this:

public static class Utilities {
    public static int Sum(int number1, int number2) {
        return number1 + number2;
    }
}

int three = Utilities.Sum(1, 2);

该类(通常)不应具有任何字段或属性. (除非您希望在代码中共享某个对象的单个实例，否则可以将static设置为只读属性.

The class should (usually) not have any fields or properties. (Unless you want to share a single instance of some object across your code, in which case you can make a static read-only property.
