在我的Create View我有

@using (Html.BeginForm(new { ReturnUrl = ViewBag.ReturnUrl, FormMethod.Post, enctype = "multipart/form-data" }))
        {
            @Html.AntiForgeryToken()
            @Html.ValidationSummary(true)

        <div>
            <h2>New Task</h2>
            <ol style="list-style-type: none;">
                <li>
                    @Html.LabelFor(m => m.Title, htmlAttributes: new { @class = "formlabel" })
                    @Html.TextBoxFor(m => m.Title)
                    @Html.ValidationMessageFor(m => m.Title)
                </li>
                <li>
                    @Html.LabelFor(m => m.Description, htmlAttributes: new { @class = "formlabel" })
                    @Html.TextAreaFor(m => m.Description)
                    @Html.ValidationMessageFor(m => m.Description)
                </li>
                <li>
                    @Html.LabelFor(m => m.Deadline, htmlAttributes: new { @class = "formlabel" })
                    @Html.TextBoxFor(m => m.Deadline, htmlAttributes: new { id = "date-picker", type = "text", @class = "hasDatepicker" })
                    @Html.ValidationMessageFor(m => m.Deadline)
                </li>
                <li>
                    @Html.LabelFor(m => m.RankID, htmlAttributes: new { @class = "formlabel" })
                    @Html.DropDownList("RankID", null, htmlAttributes: new { @class = "standselect" })
                    @Html.ValidationMessageFor(m => m.RankID)
                </li>
                <li>
                    @Html.LabelFor(m => m.PriorityID, htmlAttributes: new { @class = "formlabel" })
                    @Html.DropDownList("PriorityID", null, htmlAttributes: new { @class = "standselect" })
                    @Html.ValidationMessageFor(m => m.PriorityID)
                </li>
                <li>
                    <label for="uploadFile">Files</label>
                    <input type="file" name="uploadFile" id="uploadFile" />
                </li>
                <li style="margin: 20px 0 0 32px;">
                    <input type="submit" class="ghButton btn btn-navy" value="Create" />
                </li>
            </ol>
        </div>
    }

在我的Controller我有

        [HttpPost]
        public ActionResult Create(ETaskModel taskModel, HttpPostedFileBase uploadFile)
        {
            var tasksServ = new TasksService();

            //var files = Request.Files;//files
            var upFiles = uploadFile;//up files

            //returning recently created task
            DataAccess.Task createdTask;
            tasksServ.Create(taskModel.Title, taskModel.RankID, SessionHelper.User.ID, taskModel.Deadline, taskModel.Description, taskModel.PriorityID,
                null,   //---------documents
                null,   //implementator users
                out createdTask);


            var generalServ = new General();
            ViewBag.RankID = new SelectList(generalServ.GetRanks(), "RankID", "RankValue", taskModel.RankID);
            ViewBag.PriorityID = new SelectList(generalServ.GetPriorities(), "PriorityID", "Name", taskModel.PriorityID);
            return View(taskModel);
        }

提交时，我在我的ETaskModel taskModel对象中收到数据。但HttpPostedFileBase files总是空的。也Request.Files.Count总是0；

我有什么问题。可以同时上传文件和接收ETaskModel数据吗？

PS uploadFile文件上传的文件名和控制器方法参数是一样的！

我认为您使用了错误的重载版本BeginForm

反而

Html.BeginForm(null, null, FormMethod.Post, new { ReturnUrl = ViewBag.ReturnUrl, enctype = "multipart/form-data" })

那是因为您的 Action 中的参数需要命名uploadFile，而不是与表单上提供的参数files相匹配。id然后，选择的文件将可用。

Try adding the HttpPostedFileBase to your model,

    public class ETaskModel 
    {
      public string Title {get; set;}
      public string Description{get; set;}
      .
      .
      public HttpPostedFileBase uploadFile {get; set;}
    }

and in your controller,

        [HttpPost]
        public ActionResult Create(ETaskModel taskModel)
        {
          .
          .
        }

Didnt check the code, but this might work, Hope this helps.
