Question

我有两个实体Team，MainEntry。现在，我希望在MainEntry视图中进行下拉时获取所有团队详细信息在MVC中。换句话说，在MainEntry视图中，我想在下拉列表中获取所有团队详细信息。我使用VS-2015，MVC5，EF6与Code首次迁移。

 public class Team
    {     
        public int TeamId { get; set; }
        public string TeamName { get; set; }
        public string TeamAge { get; set; }
        public string TeamLocation { get; set; }    
     }


 public class MainEntry
 {     
        public int MainEntryId { get; set; }
        public string TeamAssignment { get; set; }
        public string Role { get; set; }
        public string Series { get; set; }  
        public string Stock { get; set; } 
        public string Points { get; set; }
        public sting Teamname {get; set;}   //(dropdown fill)
        public string Teamage {get;set;}    //(dropwon fill)
        public string TeamLocation {get;set;} //(dropwon fill)
 }

Answer 1

您可以填写下拉列表，例如

ViewBag.Teamnames = _db.Team.Select(c => new SelectListItem
                {
                    Text = c.Teamname ,
                    Value = c.MainEntryId.ToString(),
                    Selected = true
                });

并在您看来：

@Html.DropDownList(
    "TeamName", 
    (IEnumerable<SelectListItem>)ViewBag.Teamnames, 
    new { style = "max-width: 600px;" }
)

另一种方式

我通常会创建一个包含模型的视图模型，如果您想在模型中进行收集，可以更改模型，并更新迁移配置文件

 public class MainEntry  {     
        public int MainEntryId { get; set; }
        public string TeamAssignment { get; set; }
        public string Role { get; set; }
        public string Series { get; set; }  
        public string Stock { get; set; } 
        public string Points { get; set; }
        public IEnumerable<Team> Teamname { get; set; }//(dropwon fill)
        public IEnumerable<Team> Teamage //(dropwon fill)
        public IEnumerable<Team> TeamLocation //(dropwon fill)  }

如何在MVC 5中获取其他主要实体的团队实体细节？
