C# EditorTemplate中的MVC字典

我不想把字典和视图绑定在一起。但该模型似乎是无效的。 棘手的是，我在另一个视图中使用了一个视图，但我不知道我的错误在哪里

以下是我目前的代码：

第一款车型：

public class QuantityAndSize
{
    private Dictionary<String, int> m_Size;

    public decimal Quantity {get;set;}
    public Dictionary<string,int> Size 
    {
        get
        {
            return m_Size;
        }
        set 
        {
            m_Size = value;
        }
    }
    public int SelectedItem {get;set;}

    public QuantityAndSize() 
    {
        Quantity = 0;
        m_Size = new Dictionary<string, int>();
        SelectedItem = 0;
    }
}

我在这里看到了NewItemDeliveryModel的视图

public class NewItemDeliveryModel
{
    #region - member -
    private string m_Subject;
    private QuantityAndSize m_ShortfallQuantity;
    #endregion

    #region - properties

    [Display(Name = "Betreff")]
    public string Subject
    {
        get { return m_Subject; }
        set { m_Subject = value; }
    }

    [Display(Name = "Fehlmenge")]
    public QuantityAndSize ShortfallQuantity
    {
        get { return m_ShortfallQuantity; }
        set { m_ShortfallQuantity = value; }
    }

    #endregion

    #region - ctor -

    public NewItemDeliveryModel() 
    {
        m_ShortfallQuantity = new QuantityAndSize();
    }

    #endregion
}

@model Web.Models.NewItemDeliveryModel
@{
    ViewBag.Title = "NewItemDelivery";
}

<h2>NewItemDelivery</h2>
@using (Html.BeginForm())
{
    <div class="form-horizontal">
        <div class="form-group">
            @Html.LabelFor(model => model.Subject, new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.Subject)
                @Html.ValidationMessageFor(model => model.Subject)
            </div>
        </div>

        <div class="form-group">
            @Html.LabelFor(model => model.ShortfallQuantity, new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.ShortfallQuantity)
                @Html.ValidationMessageFor(model => model.ShortfallQuantity)
            </div>
        </div>
    </div>
}

尝试将模型传递给视图

public class NewItemDeliveryController : Controller
{
// GET: NewItemDelivery
public ActionResult Index()
{
    var model = new NewItemDeliveryModel(){*Set your Dictionnary here*};
    return View("NewItemDelivery",model);
}
}

---

在此，您需要将模型传递到视图中，如下所示：

// GET: NewItemDelivery
    public ActionResult Index()
    {
        var myModel = new NewItemDeliveryModel();
        return View("NewItemDelivery", myModel);
    }

旁注：从MVC 6开始，您将能够直接向视图注入依赖性

public class NewItemDeliveryController : Controller
{
// GET: NewItemDelivery
public ActionResult Index()
{
    var model = new NewItemDeliveryModel(){*Set your Dictionnary here*};
    return View("NewItemDelivery",model);
}
}

您是否向视图传递了任何内容？没有，我以为该模型是由@model Web.Models.Structures自动绑定的。QuantityAndSize@Bongo它将自动绑定。但是你应该把它填满。如下所示：

ViewData.Model=newNewItemDeliveryModel（）View（）之前执行code>。你应该在Controller中初始化你的字典。谢谢。这是正确的answer@Neelwas first=）但你总是可以胜过其他一些答案，很高兴它有帮助@Bongo:）
// GET: NewItemDelivery
    public ActionResult Index()
    {
        var myModel = new NewItemDeliveryModel();
        return View("NewItemDelivery", myModel);
    }
