Question

我有一个自定义类

public class BloggerViewModel
{        
    public Person Blogger;
    public List<BloggerWebsite> BloggerWebsites;
}

我传入视图

[HttpGet]
    public ActionResult Edit(int id)
    {
        blogger = GetById(id);            
        var WebSites = GetBloggersWebsites(Id);            
        var BloggerViewModel = new BloggerViewModel();
        BloggerViewModel.Blogger = blogger;
        BloggerViewModel.BloggerWebsites = WebSites;
        return View(BloggerViewModel);
    }

然后当我回到编辑动作

时

[HttpPost]
public ActionResult Edit(BloggerViewModel entity)
{
    return View(entity);
}

entity为空。

我的观点是这样的（我拿出了你不需要看的所有代码。比如大多数文本框绑定）

@model Bloginect.Model.Models.BloggerViewModel

<h2>Edit</h2>

@using (Html.BeginForm()) {
@Html.ValidationSummary(true)

<fieldset>
    <legend>Person</legend>

    @Html.HiddenFor(model => model.Blogger.Id)

    <div class="editor-label">
        @Html.LabelFor(model => model.Blogger.FirstName)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.Blogger.FirstName)
        @Html.ValidationMessageFor(model => model.Blogger.FirstName)
    </div>

    <div class="editor-label">
        @Html.LabelFor(model => model.Blogger.LastName)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.Blogger.LastName)
        @Html.ValidationMessageFor(model => model.Blogger.LastName)
    </div>

        <div class="editor-field">

            @if (Model.BloggerWebsites[0].Website != null)
            {
                Html.EditorFor(model => model.BloggerWebsites[0].Website);
            }
            else
            {
                @Html.TextBox("Website1")
            }

        </div>

        <div class="editor-field">
            @if (Model.BloggerWebsites[1].Website != null)
            {
                Html.EditorFor(model => model.BloggerWebsites[0].Website);
            }
            else
            {
                @Html.TextBox("Website2")
            }
        </div>

        <div class="editor-field">
            @if (Model.BloggerWebsites[2].Website != null)
            {
                Html.EditorFor(model => model.BloggerWebsites[0].Website);
            }
            else
            {
                @Html.TextBox("Website3")
            }          
        </div>

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

<div>
    @Html.ActionLink("Back to List", "Index")
</div>

我做错了吗？我已经检查了其他一些类似问题的答复，他们没有回答我的问题。
