如何在 MVC 中使用多维数组初始化模型 ASP.Net

Question

使用多个数组初始化模型。

我已经尝试初始化，但它不起作用。

namespace ArrayTest.Models
{
    public class Question
    {
        public string question { get; set; }
        public string[] option { get; set; }
        public string[] score { get; set; }
    }
}
public class DefaultController : Controller
{
    public ActionResult Index()
    {
        IEnumerable<Question> x = new List<Question>
        {
            new Question(){ question = "Question1", option = { "abc","cde","efg"}, score = { "abc", "cde", "efg" } },
            new Question(){},
            new Question(){},
            new Question(){}
        };
        return View(x);
    }
}

我希望此模型被初始化并发送到视图。

Answer 1

string[]没有

.Add()方法，因此option = { "abc", "cde", "efg"}不起作用。您需要创建数组并初始化数组：

var list = new List<Question>
{
    new Question()
    {
        question = "Question1",
        option = new string[] { "abc", "cde", "efg"},
        score = new string[] { "abc", "cde", "efg" }
    },
    new Question(){},
    new Question(){},
    new Question(){}
};

步骤 1 ：在模态中添加一个构造函数，如下所示，

 public class Question
    {
        public string question { get; set; }
        public string[] option { get; set; }
        public string[] score { get; set; }
        public Question(string question, List<string> option, List<string> score)
        {
            this.question = question;
            this.option = option.ToArray();
            this.score = score.ToArray();
        }
    }

第 2 步：修改控制器方法，如下所示，

 IEnumerable<Question> x = new List<Question> {
                new Question("Question1", new List<string>{"cde","efg"}, new List<string> { "abc", "cde", "efg" }),
                new Question("Question2", new List<string>{"cde","efg"}, new List<string> { "abc", "cde", "efg" }) } ;

如果使用此列表，则可以使用 。Add(( 方法也是如此。
