c# - 在模型中声明列表

Question

我有一个场景，我不想将模型作为 Ienumerable 列表传递到 Razor View 。

public class School
{
   public int ID { get; set; }
   public string Name { get; set; }
   public string Address { get; set; }
}

我需要传递模型来查看，如下所示。

@model Doc.Web.Models.Common.School

不像

@model IEnumerable<Doc.Web.Models.Common.School>

所以，我在同一模型中贴标了一个列表

public class School
{
    public School()
    {
        lstSchool = new List<School>();
    }

    public int ID { get; set; }
    public string Name { get; set; }
    public string Address { get; set; }

    public List<School> lstSchool { get; set; }
}

然后在 Controller 中

public ActionResult Index()
{
   School model= new School();
   SchoolRepository rep = new SchoolRepository();
   model.lstSchool= rep.GetData();//Read list of schools from database
   return View(model);
}

这是实现这一目标的正确方法吗？

Answer 1

为什么要将 @model Doc.Web.Models.Common.School 传递给 View ？在 View 中需要“列表”的地方。

这是你可以尝试的东西......

类结构:创建一个 SchoolList 类

public class School
{
    public int ID { get; set; }
    public string Name { get; set; }
    public string Address { get; set; }
}

public class SchoolList 
{
    public List<School> Schools { get; set; }
}

传递给 View :

@model Doc.Web.Models.Common.SchoolList

Controller :

public ActionResult Index()
{
    SchoolList model= new SchoolList();
    SchoolRepository rep = new SchoolRepository();

    //Read list of schools from database
    model.Schools = rep.GetData(); 

    return View(model);
}

因此，您无需将 IEnumerable 传递给 View 即可完成工作。
