好的,我刚刚开始使用C#并尝试从C ++的基本方面过渡。而且我不知道如何从用户输入到类中填充数组列表。 我的代码如下所示:

namespace L1
{
    public class Users
    {
        private int username;


        public Users(string username)
        {
            this.username = username;    
        }

        public string Takename() { return username; }    
    }

    class Program
    {
        static void Main(string[] args)
        {
            List<Users> users = new List<Users>();
            for(int i=1; i<=4; i++)
            {
               Console.Write("Enter username: ");
               Users user = new Users();
               user.username= Console.Readline();
               users.Add(user);
            }      
        }               
    }
}

您的“用户名”属性为int时应为string

此外,该属性的范围是私有的,只能在类的方法中修改。

因此要么将范围设置为公开,要么只使用:

User user = new Users(Console.ReadLine());

这是基于我告诉你的固定代码:

namespace L1
{
    public class Users
    {
        private string username;


        public Users(string username)
        {
            this.username = username;    
        }

        public string Takename() { return username; }    
    }

    class Program
    {
        static void Main(string[] args)
        {
            List<Users> users = new List<Users>();
            for(int i=1; i<=4; i++)
            {
               Console.Write("Enter username: ");
               Users user = new Users(Console.Readline());
               users.Add(user);
            }      
        }               
    }
}

我不确定您面临的问题究竟是什么,但以下内容对您有所帮助:

// Renamed to User as we are representing only one user
public class User
{
    // Renamed from userName to Name
    // Made a string to be consistent with the constructor
    // Made it a public property
    public string Name { get; set; }

    public User(string name)
    {
        Name = name;
    }

    public string TakenName() { return Name; }
}

class Program
{
    static void Main(string[] args)
    {
        List<User> users = new List<User>();

        // for loops in c# typically are zero based
        for (int i = 0; i < 4; i++)
        {
            Console.Write("Enter Name: ");
            string name = Console.ReadLine();
            User user = new User(name);
            users.Add(user);
        }
    }
}
