Request.Files.Count始终为0，而​​在MVC 5上传图片 [英] Request.Files.Count always 0 while uploading image in MVC 5

问题描述

我有一些字符串字段和图像模型的帖子控制器。确切的相同code适用于MVC4但在MVC 5 Request.Files.Count始终为0

I have a Post controller on a model with some string fields and an image. Exact identical code works on MVC4 but in MVC 5 the Request.Files.Count is always 0

我的模型具有字节[]的图像，而不是HttpPostedFileBase

My model has byte[] for image rather than HttpPostedFileBase

我的观点：

@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" />
}

我试图忽略data_ajax =假，但没有用。

I have tried omitting data_ajax = "false" but no use.

我的帖子控制器如下：

    [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始终为零，我不知道为什么？
我抄了从另一个MVC4项目中，它工作正常，两个视图和控制器code。

In the debugger I see that the Request.Files.Count is always zero, I don't know why? I have copied over both the view and controller code from another MVC4 project where it works fine.

而在IE开发窗口，我看到表单主体是空的。

And in the IE Developer window I see that the form body is empty.

推荐答案

我浪费了那么多时间和事实证明，所有我需要做的是使用的名称属性以及

I wasted so much time and it turns out that all I needed to do was to use the name attribute as well

 <input type="file" name="somename"> 

的名称属性缺失在我的新项目。

the name attribute was missing in my new project.
