c# - 我需要一个解决方案来消除类中的公共(public)字符串

Question

我是编码的新手，只是学习如何调用类(class)成员。如果我想创建和存储多个字段并从控制台访问它们，请推荐正确的方法。我被告知类中的多个公共(public)变量效率不高。请指教。谢谢!

public class MainClass
{

    class IronMan
    {
        public string fName = "Tony";
        public string lName = "Stark";
        public int Age = 50;

    }

    class CaptainAmerica
    {
        public string fName = "Steve";
        public string lName = "Rogers";
        public int Age = 126;
    }

    public static void Main()
    {
        CaptainAmerica avenger = new CaptainAmerica();
        Console.WriteLine(avenger.fName);
    }  
}

Answer 1

IronMan 和 CaptainAmerica 应该是对象而不是类，class 应该是通用的

在你的例子中，你的类应该是 SuperHero 例如

public class SuperHero
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public int Age { get; set; }

    public SuperHero(string FirstName, string LastName, int Age)
    {
        this.FirstName = FirstName;
        this.LastName = LastName;
        this.Age = Age;        
    }
}

然后，在您的 Main() 中，您应该创建 SuperHero

的实例

public class MainClass
{
    public static void Main()
    {
        //This is a instance of SuperHero, specific, Tony Stark
        SuperHero ironman = new SuperHero("Tony","Stark",50);
        Console.WriteLine(ironman.FirstName);
        //This is a instance of SuperHero, specific, Steve Rogers
        SuperHero captain = new SuperHero("Steve","Rogers",126);
        Console.WriteLine(captain.FirstName);
    }
}

我建议您在开始编程之前阅读有关 OO 的内容(假设您将使用面向对象范式)
