在MVC 5中上传图像时,asp.net-mvc – Request.Files.Count总是为

我的模型有byte [],而不是HttpPostedFileBase

我的看法：

@using (Html.BeginForm("Create","HotelManager",FormMethod.Post,new { enctype = "multipart/form-data",data_ajax = "false" }))
{
    @Html.AntiForgeryToken()
    @Html.TextBoxFor(model => model.Title,new { @class = "form-control" })
    @Html.TextAreaFor(model => model.Description,new { @class = "form-control",@rows = "7" })
    <input type="file" class="form-control filestyle">
    <input type="submit" value="Submit" class="btn btn-block" />
}

我已经尝试省略了data_ajax =“false”,但没有用.

我的邮政主管如下：

[HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Create([Bind(Include = "Title,Description,Image")] Hotel hotel)
    {
        if (ModelState.IsValid)
        {
            // deal with the uploaded file
            if (Request.Files.Count > 0)
            {
                HttpPostedFileBase file = Request.Files[0];

                if (file != null && file.ContentLength > 0)
                {
                    // Code to process image,resize,etc goes here
                }
            }

        // Other code to add the hotel to db goes here
    }

在调试器中,我看到Request.Files.Count总是为零,我不知道为什么？
我已经从另一个MVC4项目中复制了视图和控制器代码,它的工作正常.

在IE Developer窗口中,我看到窗体正文是空的.
