上传文件始终为空

Question

当我尝试上传文件时，它始终为空，但用户名已通过。

<div class="container">
    @using(Html.BeginForm("Upload", "ADImage", FormMethod.Post, new { enctype = "mulipart/form-data" }))
    { 
        <fieldset>
            <legend>AD Image Upload</legend>
            <label>AD Username</label>
            <div class="input-control text" data-role="input-control">
                <input type="text" name="username" placeholder="Username" />
                <button class="btn-clear" tabindex="-1" type="button"></button>
            </div>
            <label>Choose File</label>
            <div class="input-control file info-state" data-role="input-control">
                <input type="file" name="file" tabindex="-1" style="z-index: 0;" />
                <input type="text" id="input_file_wrapper" readonly style="z-index: 1; cursor: default;" />
                <button class="btn-file" type="button"></button>
            </div>

            <button type="submit" value="Submit">Submit</button>
        </fieldset>
    }
</div>

控制器

    [HttpPost]
    public ActionResult Upload(HttpPostedFileBase file, string username)
    {
        if (string.IsNullOrWhiteSpace(username))
        {
            ViewBag.IsUserValid = false;
        }
        else if (file == null | file.ContentLength.Equals(0))
        {
            ViewBag.IsFileValid = false;
        }
        else
        {
            byte[] fileBytes = ReadFile(file.InputStream);
        }
        return RedirectToAction("Index");
    }

Answer 1

您在表单的 enctype 字段中有错字。是

"mulipart/form-data"

但应该是

"multipart/form-data"

注意缺少的 "t"。
