Answer 1

You need to make sure your <form> as the attribute enctype="multipart/form-data" if you want to populate Request.Files

Using HTML helper:

@using (Html.BeginForm("ActionName",
                "ControllerName",
                FormMethod.Post,
                new { enctype = "multipart/form-data" }))

If you are not using HTML Helper then add the attribute to your form tag.

<form method="POST" enctype="multipart/form-data" action="/SomeUrl">

Try this it will be helpful

My View Code

@using (Html.BeginForm("Index", "ImportData", null, FormMethod.Post, new { enctype = "multipart/form-data" }))
{
    @Html.AntiForgeryToken()
    @Html.ValidationSummary()
    <div class="row">
        <div id="radio" class="col-lg-12 col-md-12 col-sm-12 col-xs-12">
            <div class="input-group col-lg-4 col-md-4 col-sm-12 col-xs-12">
                <input type="file" id="dataFile" name="upload" class="btn btn-info" />
           </div>
        </div>
    </div>
    <br />
    <div class="row">
        <div id="radio" class="col-lg-12 col-md-12 col-sm-12 col-xs-12" align="center">
            <div class="input-group col-lg-12 col-md-12 col-sm-12 col-xs-12">
                <input type="submit" value="Upload" class="btn btn-primary" />
            </div>
        </div>
    </div>
}

My Controller code

    [HttpPost]
    public ActionResult Index(HttpPostedFileBase upload)
    {
        if (ModelState.IsValid)
        {

            if (upload != null && upload.ContentLength > 0)
            {


            }
            else
            {
                ModelState.AddModelError("File", "Please Upload Your file");
            }
        }
        return View();
    }

您的HTML没有<form>标记，它告诉浏览器如何处理提交按钮的单击。
