c# – 带继承的MVC Complex模型绑定,嵌套的viewModels和部分视图

这是简化的架构：

//The viewModel being passed to the view
public class RunnerIndexViewModel
{
    public RegisterViewModel User { get; set; }

    public TrainerViewModel TrainerVM { get; set; }

    public RunnerBase Runner { get; set; }

    [Display(Name = "AddContact",ResourceType = typeof(MyRessources))]
    public bool AddContact { get; set; }
}

public class RegisterViewModel
{
    // various simple type properties here
}

public class TrainerViewModel
{
    // various properties here
    public Unit unit { get; set; }

    public List<SelectListItem> ListStatut { get; set; }
}

public abstract partial class RunnerBase
{
    // entity framework class with associations
}

public class RedRunner : RunnerBase
{
    // entity framework class with associations
}

public class BlueRunner : RunnerBase
{
    // entity framework class with associations
}

以下是从控制器接收模型的主视图(简化)：

@model Web.Models.Fournisseurs.FournisseurIndexViewModel

@using (Html.BeginForm())
{
    @Html.AntiForgeryToken()

    @Html.Partial("PartialTrainer",Model.TrainerVM)
    @Html.Partial("PartialRunner",Model.Runner as RedRunner)
    @Html.Partial("PartialUser",Model.User)
}

PartialTrainer和PartialUser的观点没什么特别之处,所以这里是从实体框架中获取基类的PartialRunner视图：

@model RunnerBase

@* Show Various fields from RunnerBase ... *@

@if (Model is RedRunner)
{
    @* show properties specific to RedRunner *@
}
else if (Model is BlueRunner)
{
    @* show properties specific to BlueRunner *@
}

从控制器我将RedRunner或BlueRunner传递给Runner属性.所有viewModel的所有字段都显示良好,但在提交表单时,我只设法获取AddContact值…

如何获取其他视图模型的值以及Runner类中的值？
