Ajax.BeginForm是否支持文件上传？

Question

我使用HttpPostedFileBase作为文件的模型，但是文件来了 控制器无效，我想使用AjaxForm，因为Asp.net不提供我需要发布此抛出ajax的常规BeginForm吗？

   @using (Ajax.BeginForm("UploadImg", "Controller", Object,
  new AjaxOptions { HttpMethod ="Post", OnComplete = "Something();" },
  new { enctype = "multipart/form-data" }))
                {
                    @Html.AntiForgeryToken()

                    <div class="form-horizontal">

                        @Html.ValidationSummary(true, "", new { @class = "text-danger" })

                        <div class="form-group">

                            <div class="col-lg-7">
@Html.TextBoxFor(model => model.File, new { type = "file", @class = "form-control", required = "required" })

                <input type="submit" value="Upload" class="btn-primary" />


                            </div>
                        </div>
                    </div>
        }
