ASP.NET MVC 上传图片怎么总是为空

悬赏园豆：10 [已解决问题] 解决于 2015-09-10 12:12

代码如下：

<form action="~/Home/Indexs" method="post" enctype="multipart/form-data">

  <label for="file1">Filename:</label>
  <input type="file" name="files1" id="file1" />


  <input type="submit"  />
</form>

后台

[HttpPost]
        public ActionResult Indexs(HttpPostedFileBase[] files)
        {
           var t=Request.Files[0];
            if (files != null)
            {
                DateTime time = DateTime.Now;
                foreach (var file in files)
                {
                    if (file.ContentLength > 0)
                    {
                        var fileName = Path.GetFileName(file.FileName);
                        var path = Path.Combine(Server.MapPath("~/App_Data/uploads/" + time.ToString()), fileName);
                        file.SaveAs(path);
                    }
                }
            }
            return RedirectToAction("Index");
        }
