我有以下剃刀代码：

  <div class="container">
        @Html.ValidationSummary(false)
        @using (Html.BeginForm("EncryptFile", "Encryption", new { returnUrl = Request.Url.AbsoluteUri }, FormMethod.Post, new { @id = "encryptionform", @class = "form-horizontal" }))
        {

            <div class="form-group">
                @Html.Label("File", new { @class = "control-label col-md-2" })
                <div class="col-md-10">
                    <input type="file" id="encryptfilefield" name="uploadedfile" enctype='multipart/form-data'/>
                </div>
            </div>


                    <button type="submit" id="encryptfilebutton">Encrypt</button>
                    <button id="decryptfilebutton" type="button">Decrypt</button>
                    <button id="reencryptfilebutton" type="button">Re-Encrypt</button>

        }
    </div>

当我单击“加密”按钮时，将调用以下控制器代码：

  [HttpPost]
    public ActionResult EncryptFile(string uploadedfile)
    {
       /*process the file without uploading*/
      return Json(new { status = "success", message = "Encrypted!" });
    }

当我单击加密按钮时，我可以执行此操作，但uploadedfile字符串始终以 …

我需要使用带有RAZOR的MVC3将多个文件上传到Web服务器.我有以下代码.在控制器中,我的文件数为零.如何更正它以获取上传的文件的实际数量并获取内容？

public class MyFileController : Controller
{

    public ActionResult MyFileProcessActionTest()
    {
        return View();
    }

    [HttpPost]
    public ActionResult MyFileProcessActionTest(IEnumerable<System.Web.HttpPostedFileBase> files)
    {

        int fileCount = files.Count<System.Web.HttpPostedFileBase>();
        return RedirectToAction("Index");
    }
}

视图

@{
ViewBag.Title = "MyFileProcessActionTest";
}

<h2>MyFileProcessActionTest</h2>

@using (Html.BeginForm())
{

<input type="file" name="files" id="file1" />
<input type="file" name="files" id="file2" />

<input type="submit"  />

}
