我想在一个视图中有2个模型。页面包含LoginViewModel和RegisterViewModel。
e.g.
public class LoginViewModel
{
public string Email { get; set; }
public string Password { get; set; }
}
public class RegisterViewModel
{
public string Name { get; set; }
public string Email { get; set; }
public string Password { get; set; }
}
我需要做另一个ViewModel持有这2个ViewModel吗?
public BigViewModel
{
public LoginViewModel LoginViewModel{get; set;}
public RegisterViewModel RegisterViewModel {get; set;}
}
我需要将验证属性带到视图中。这就是为什么我需要ViewModels。
有没有其他的方法，比如(没有BigViewModel):
@model ViewModel.RegisterViewModel
@using (Html.BeginForm("Login", "Auth", FormMethod.Post))
{
@Html.TextBoxFor(model => model.Name)
@Html.TextBoxFor(model => model.Email)
@Html.PasswordFor(model => model.Password)
}
@model ViewModel.LoginViewModel
@using (Html.BeginForm("Login", "Auth", FormMethod.Post))
{
@Html.TextBoxFor(model => model.Email)
@Html.PasswordFor(model => model.Password)
}
将这个ModelCollection.cs添加到您的模型中
using System;
using System.Collections.Generic;
namespace ModelContainer
{
public class ModelCollection
{
private Dictionary<Type, object> models = new Dictionary<Type, object>();
public void AddModel<T>(T t)
{
models.Add(t.GetType(), t);
}
public T GetModel<T>()
{
return (T)models[typeof(T)];
}
}
}
控制器:
public class SampleController : Controller
{
public ActionResult Index()
{
var model1 = new Model1();
var model2 = new Model2();
var model3 = new Model3();
// Do something
var modelCollection = new ModelCollection();
modelCollection.AddModel(model1);
modelCollection.AddModel(model2);
modelCollection.AddModel(model3);
return View(modelCollection);
}
}
视图:
enter code here
@using Models
@model ModelCollection
@{
ViewBag.Title = "Model1: " + ((Model.GetModel<Model1>()).Name);
}
<h2>Model2: @((Model.GetModel<Model2>()).Number</h2>
@((Model.GetModel<Model3>()).SomeProperty
将这个ModelCollection.cs添加到您的模型中

namespace ModelContainer
{
public class ModelCollection
{
private Dictionary<Type, object> models = new Dictionary<Type, object>();
public void AddModel<T>(T t)
{
models.Add(t.GetType(), t);
}
public T GetModel<T>()
{
return (T)models[typeof(T)];
}
}
}
控制器:
public class SampleController : Controller
{
public ActionResult Index()
{
var model1 = new Model1();
var model2 = new Model2();
var model3 = new Model3();
// Do something
var modelCollection = new ModelCollection();
modelCollection.AddModel(model1);
modelCollection.AddModel(model2);
modelCollection.AddModel(model3);
return View(modelCollection);
}
}
视图:
enter code here
@using Models
@model ModelCollection
@{
ViewBag.Title = "Model1: " + ((Model.GetModel<Model1>()).Name);
}
<h2>Model2: @((Model.GetModel<Model2>()).Number</h2>
@((Model.GetModel<Model3>()).SomeProperty
我想说的是，我的解决方案就像这个stackoverflow页面上提供的答案:ASP。NET MVC 4，多个模型在一个视图?
然而，在我的情况下，他们在他们的控制器中使用的linq查询不适合我。
这就是所谓的查询:
var viewModels =
(from e in db.Engineers
select new MyViewModel
{
Engineer = e,
Elements = e.Elements,
})
.ToList();
因此，“在您的视图中，只需指定您正在使用视图模型的集合”对我来说也不适用。
然而，稍微改变一下这个解决方案确实对我有用。这是我的解决方案，希望对大家有所帮助。
这是我的视图模型，我知道我将只有一个团队，但该团队可能有多个板(顺便说一下，我在我的Models文件夹中有一个ViewModels文件夹，因此有命名空间):
namespace TaskBoard.Models.ViewModels
{
public class TeamBoards
{
public Team Team { get; set; }
public List<Board> Boards { get; set; }
}
}
这是我的控制器。这是与上面引用的链接中的解决方案最显著的区别。我构建了ViewModel以不同的方式发送到视图。
public ActionResult Details(int? id)
{
if (id == null)
{
return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
}
TeamBoards teamBoards = new TeamBoards();
teamBoards.Boards = (from b in db.Boards
where b.TeamId == id
select b).ToList();
teamBoards.Team = (from t in db.Teams
where t.TeamId == id
select t).FirstOrDefault();
if (teamBoards == null)
{
return HttpNotFound();
}
return View(teamBoards);
}
在我看来，我没有将它指定为列表。我只做@model taskboard。models。viewmodels。“然后，当我迭代团队的板时，我只需要每个。以下是我的观点:
@model TaskBoard.Models.ViewModels.TeamBoards
@{
ViewBag.Title = "Details";
}
<h2>Details</h2>
<div>
<h4>Team</h4>
<hr />
@Html.ActionLink("Create New Board", "Create", "Board", new { TeamId = @Model.Team.TeamId}, null)
<dl class="dl-horizontal">
<dt>
@Html.DisplayNameFor(model => Model.Team.Name)
</dt>
<dd>
@Html.DisplayFor(model => Model.Team.Name)
<ul>
@foreach(var board in Model.Boards)
{
<li>@Html.DisplayFor(model => board.BoardName)</li>
}
</ul>
</dd>
</dl>
</div>
<p>
@Html.ActionLink("Edit", "Edit", new { id = Model.Team.TeamId }) |
@Html.ActionLink("Back to List", "Index")
</p>
我对ASP还是个新手。NET MVC，所以我花了一点时间来弄清楚。所以，我希望这篇文章能帮助人们在更短的时间内为他们的项目找到答案。: -)
