public class RegisterViewModel
{
    //Plain POCO Properties
    public RegisterModel RegisterModel { get; set; }

    //Meant to be used in SelectLists.
    public IEnumerable<CityModel> Cities { get; set; }
    public IEnumerable<CountryModel> Countries { get; set; }
}

以下是这些课程：

public class RegisterModel
{
    [Required]
    [Display(Name = "Usuario")]
    public string UserName { get; set; }

    [Required]
    [DataType(DataType.EmailAddress)]
    [Display(Name = "Correo")]
    public string Email { get; set; }

    [Required]
    [StringLength(100, ErrorMessage = "Su {0} debe tener al menos {2} caracteres.", MinimumLength = 6)]
    [DataType(DataType.Password)]
    [Display(Name = "Contraseña")]
    public string Password { get; set; }

    [DataType(DataType.Password)]
    [Display(Name = "Confirme Su Contraseña")]
    [Compare("Password", ErrorMessage = "Sus contraseñas no son las mismas.")]
    public string ConfirmPassword { get; set; }

    [Required]
    [Display(Name = "Nombre")]
    public string Nombre { get; set; }

    [Required]
    [Display(Name = "Apellido")]
    public string Apellido { get; set; }

    [Required]
    [Display(Name = "Direccion")]
    public string Address { get; set; }

    [Required]
    [Display(Name = "Telefono Fijo")]
    public string Telephone { get; set; }

    [Required]
    [Display(Name = "Celular")]
    public string MobilePhone { get; set; }

    [Required]
    [Display(Name = "Fecha de Nacimiento")]
    public DateTime DateOfBirth { get; set; }

    [Required]
    [Display(Name = "Soy:")]
    public bool Sex { get; set; }

    [Required]
    [Display(Name = "Carnet")]
    public int Carnet { get; set; }
}

public class CityModel
{
    [HiddenInput(DisplayValue = false)]
    public int CityId { get; set; }

    [Required]
    [Display(Name = "Ciudad")]
    public string Name { get; set; }      
}

public class CountryModel
{
    [HiddenInput(DisplayValue = false)]
    public int CountryId { get; set; }

    [Required]
    [Display(Name = "Pais")]
    public string Name { get; set; } 
}

以下是我在视图中调用 RegisterViewModel 的方式：

@model Foodiggly.WebUI.Models.RegisterViewModel

@using (Html.BeginForm()) {
    @Html.ValidationSummary(true)
    <fieldset>
        <legend>RegisterViewModel</legend>

        @Html.EditorForModel()

        <p>
            <input type="submit" value="Create" />
        </p>
    </fieldset> 
}

这个错误是因为我的 ViewModel 本身没有任何注释而引起的吗？我在哪里可以正式读到这个？我设法在网上找到的只是偶尔的一两个博客，但他们在网上提到了简单的模型，而不是与诸如此类的其他对象有关系的模型。典型的外键国与人关系。

有任何想法吗？

视图模型 RegisterViewModel 没有任何“简单”属性，并且 MVC 框架不会渲染复杂属性，除非我们告诉它如何渲染这些属性。我们必须为 DisplayFor 创建显示模板，为 EditorFor 助手创建编辑器模板。检查ASP.NET MVC 2 模板以获取详细信息。另一个链接。

将您的 EditorTemplates 放在文件夹中

~/Views/Shared/EditorTemplates
or
~/Views/ControlerName/EditorTemplates

注册模型.cshtml

@model RegisterModel

@Html.LabelFor(model => model.UserName)
@Html.EditorFor(model => model.UserName)

@Html.LabelFor(model => model.Email)
@Html.EditorFor(model => model.Email)

...
...

CityModel.cshtml

@model CityModel

@Html.LabelFor(model => model.CityId)
@Html.EditorFor(model => model.CityId)

@Html.LabelFor(model => model.Name)
@Html.EditorFor(model => model.Name)

CountryModel.cshtml

@model CountryModel

@Html.LabelFor(model => model.CountryId)
@Html.EditorFor(model => model.CountryId)

@Html.LabelFor(model => model.Name)
@Html.EditorFor(model => model.Name)

我认为你是对的，你的 ViewModel 应该有注释。在我的 MVC 项目中，我对 ViewModel 进行了注释，一切正常。

请记住，您的视图对您的数据模型一无所知——它只知道您的视图模型。:-)

编辑：

[DataMember]
public class User {
public string PhoneNumber 
{ ... }

}




//[ViewModel]
public class ViewUser  {

[Required, RegularExpression(@"^\(?(\d{3})\)?[- ]?(\d{3})[- ]?(\d{4})$", ErrorMessage="Please enter a valid 10 digit phone number")]
public string ViewPhoneNumber {
}

}


View page

<div class="editor-field">
     @Html.EditorFor(model => model.Phone1)
     @Html.ValidationMessageFor(model => model.Phone1, "Please enter a valid phone number")
</div>

这有帮助吗？
