Question

我正在使用MVC4应用程序，并且有一个控制器允许用户输入一些数据。问题是我在从表单返回的所有属性中获取空值。我正在使用强类型模型，我没有看到任何名称冲突，如在几篇关于传递null模型的帖子中所建议的那样。继承我的模特

public class NewsItemView
{

    [Required]
    public string NewsTitle;

    public string NewsAuthor;

    public string NewsSummary;

    public string NewsDescription;

    public bool NewsAllowComments;

    [Required]
    public string NewsContent;

    public string NewsSourceName;
}

控制器动作（获取）

    [HttpGet]
    public ActionResult Create()
    {
        NewsItemView nv = new NewsItemView();
        return View(nv);
    }

查看：

@model NewsItemView

@using (Html.BeginForm("Create", "Service", FormMethod.Post, new { @id = "NewsForm" }))
{
@Html.LabelFor(model => model.NewsTitle)
@Html.EditorFor(model => model.NewsTitle)
<br />
@Html.LabelFor(model => model.NewsAuthor)
@Html.EditorFor(model => model.NewsAuthor)
<br />
@Html.LabelFor(model => model.NewsAllowComments)
@Html.EditorFor(model => model.NewsAllowComments)
<br />
@Html.LabelFor(model => model.NewsSummary)
@Html.EditorFor(model => model.NewsSummary)
<br />
@Html.LabelFor(model => model.NewsDescription)
@Html.EditorFor(model => model.NewsDescription)
<br />
@Html.LabelFor(model => model.NewsContent)
@Html.EditorFor(model => model.NewsContent)
<br />
@Html.LabelFor(model => model.NewsSourceName)
@Html.EditorFor(model => model.NewsSourceName)

<br />

<button type="submit" id="submitBtn">Create News</button>

}

控制器动作（帖子）

    [HttpPost]
    public ActionResult Create(NewsItemView newsModel)
    {
     //my code here
    }

如果我使用FormsCollection，我可以使用索引提取值，任何想法为什么强类型模型不起作用？

Answer 1

我已经在我的环境中重现了这个问题，而我所做的一切就是将模型字段更新为以下属性

public class NewsItemViewModel
{

    [Required]
    public string NewsTitle { get; set; }

    public string NewsAuthor { get; set; }

    public string NewsSummary { get; set; }

    public string NewsDescription { get; set; }

    public bool NewsAllowComments { get; set; }

    [Required]
    public string NewsContent { get; set; }

    public string NewsSourceName { get; set; }
}

提交表单时，Null模型在MVC中传递给控制器
