如何在for循环中使用struct元素？

Question

我是C#的新手，我正在尝试制作一个程序来提示用户输入关于8个vocalist.genre输入的信息，然后根据vocalist.genre输入的内容将这些信息分类到文本文件中。但是，当我尝试使用for循环来处理用户的输入时，我遇到了一个问题。我该怎么办？

using System;
using System.IO;

struct vocalists
{
    public string name;
    public string origin;
    public string vocalist_type;
    public string genre;
};

public class test
{

public static void Main(string[] args)
{
    vocalists vocalists1;
    vocalists vocalists2;
    vocalists vocalists3;
    vocalists vocalists4;
    vocalists vocalists5;
    vocalists vocalists6;
    vocalists vocalists7;
    vocalists vocalists8;
    
    //Vocalists inputs

    for (int i = 1; i < 9; i++)
    {
        Console.WriteLine("Enter the vocalists {0} name: ", i);
        //Here I'm supposed to do something in the format of vocalistsi.name=Console.ReadLine();
        Console.WriteLine("Enter the vocalists {0} origin: ", i);
        //Here I'm supposed to do something in the format of vocalistsi.origin=Console.ReadLine();
        Console.WriteLine("Enter the vocalists {0} type: ", i);
        //Here I'm supposed to do something in the format of vocalistsi.type=Console.ReadLine();
        Console.WriteLine("Enter the vocalists {0} genre: ", i);
        //Here I'm supposed to do something in the format of vocalistsi.genre=Console.ReadLine();
    }
    
    
    
}

}

您不能通过名称组合访问字段，所以有8个字段不是一个好主意；但是,您可以有一个字段,它是一个数组或列表：

List<Vocalist> vocalists = new List<Vocalist>();
// now use vocalists.Add(...) and vocalists[i]

或

Vocalist[] vocalists = new Vocalist[8];
// now use vocalists[i]

我还应该注意到，将vocalist作为struct是一个会伤害您的可怕想法。它可能应该是类:

class Vocalist
{
    public string Name {get;set;}
    public string Origin {get;set;}
    public string VocalistType {get;set;}
    public string Genre {get;set;}
}

或者在最坏的情况下是只读结构。
