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)
 }

当前回答

你总是可以在ViewBag或View Data中传递第二个对象。

其他回答

我建议使用Html。RenderAction和PartialViewResults来完成这个;它将允许您显示相同的数据,但每个部分视图仍然有一个单一的视图模型,并消除了对BigViewModel的需要

你的视图包含如下内容:

@Html.RenderAction("Login")
@Html.RenderAction("Register")

其中Login和Register都是你控制器中的动作,定义如下:

public PartialViewResult Login( )
{
    return PartialView( "Login", new LoginViewModel() );
}

public PartialViewResult Register( )
{
    return PartialView( "Register", new RegisterViewModel() );
}

Login & Register将是位于当前View文件夹或共享文件夹中的用户控件,并像这样:

/views/Shared/Login.cshtml: (或 /views/MyView/Login.cshtml)

@model LoginViewModel
@using (Html.BeginForm("Login", "Auth", FormMethod.Post))
{
    @Html.TextBoxFor(model => model.Email)
    @Html.PasswordFor(model => model.Password)
}

/views/Shared/Register.cshtml: (或 /views/MyView/Register.cshtml)

@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)
}

你有一个单独的控制器动作,每个动作都有视图和视图文件每个动作都完全不同,不依赖于其他任何东西。

有很多方法……

with your BigViewModel you do: @model BigViewModel @using(Html.BeginForm()) { @Html.EditorFor(o => o.LoginViewModel.Email) ... } you can create 2 additional views Login.cshtml @model ViewModel.LoginViewModel @using (Html.BeginForm("Login", "Auth", FormMethod.Post)) { @Html.TextBoxFor(model => model.Email) @Html.PasswordFor(model => model.Password) } and register.cshtml same thing after creation you have to render them in the main view and pass them the viewmodel/viewdata so it could be like this: @{Html.RenderPartial("login", ViewBag.Login);} @{Html.RenderPartial("register", ViewBag.Register);} or @{Html.RenderPartial("login", Model.LoginViewModel)} @{Html.RenderPartial("register", Model.RegisterViewModel)} using ajax parts of your web-site become more independent iframes, but probably this is not the case

你总是可以在ViewBag或View Data中传递第二个对象。

使用包含多个视图模型的视图模型:

   namespace MyProject.Web.ViewModels
   {
      public class UserViewModel
      {
          public UserDto User { get; set; }
          public ProductDto Product { get; set; }
          public AddressDto Address { get; set; }
      }
   }

你认为:

  @model MyProject.Web.ViewModels.UserViewModel

  @Html.LabelFor(model => model.User.UserName)
  @Html.LabelFor(model => model.Product.ProductName)
  @Html.LabelFor(model => model.Address.StreetName)

在你的模型和LoginViewModel和RegisterViewModel属性中创建一个新类: 公共类UserDefinedModel() { 属性a1作为LoginViewModel property a2 as RegisterViewModel } 然后在视图中使用UserDefinedModel。
