Я пытаюсь загрузить файл и некоторые данные в действие контроллера через запрос AJAX, однако параметр HttpPostedFileBase всегда равен нулю
, вот мой cshtml
<div class="modal fade" id="MyModal">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<a href="#" class="close" data-
dismiss="modal">×</a>
<h4 id="ModalTitle"></h4>
</div>
<div class="modal-body">
@using (Html.BeginForm("EditResearch",
"Admin", FormMethod.Post, new { id = "form", enctype = "multipart/form-
data" }))
{
@Html.AntiForgeryToken()
<fieldset id="SubmitForm">
@Html.HiddenFor(m => m.ResearchID,
new { @id = "ResearchID" })
<div class="input-field">
<label for="name">Journal Name </label>
</div>
<div class="form-group">
@Html.TextBoxFor(m =>
m.NameJournal, new { @id = "NameJournal", @class = "form-control",
@placeholder = "Journal Name*" })
</div>
<div class="input-field">
<label for="name">File</label>
</div>
<div class="form-group">
@Html.TextBoxFor(model => model.ResearchFile, new { @type = "file", @name = "ResearchFile", @id
=
"ResearchFile" })
@*<input name="fileresearch"
id="fileresearch" type="file" />*@
</div>
<div class="input-field">
<label for="name">
Abstract
</label>
</div>
<div class="form-group">
@Html.TextAreaFor(model =>
model.ResearchContents, new { @id = "ResearchContents", @class = "form- control", @onKeyUp = "Count(this,1000)", @onChange = "Count(this,1000)", placeholder = "Abstract", name = "name", rows
= "6", cols = "85" })
</div>
<div class="form-group">
<a href="#" class="btn btn-block
btn-danger" id="SaveStudentRecord">Save</a>
</div>
</fieldset>
}
</div>
</div>
</div>
</div>
$("#SaveStudentRecord").click(function () {
var data = $("#SubmitForm").serialize();
$.ajax({
type: "Post",
url: "/Admin/SaveDataInDatabase",
data: data,
//contentType: false,
//processData: false,
success: function (result) {
if (result) {
alert("Done.");
window.location.href =
"/Admin/EditResearch";
$("#MyModal").modal("hide");
}
else {
alert("Fill Boxes");
//window.location.href =
"/Admin/EditResearch";
//$("#MyModal").modal("hide");
}
}
})
})
вот мой контроллер
[HttpPost]
public JsonResult SaveDataInDatabase(ResearchBL model,
HttpPostedFileBase ResearchFile)
{
try
{
if (Session["user"] != null)
{
ViewBag.Message = "";
string Err = "";
string userID = Session["user"].ToString();
ResearchModel researchObj = new ResearchModel();
bool Check = researchObj.SaveDataInDatabase(model,
userID, ResearchFile, ref Err);
ViewBag.Message = Err;
return Json(Check, JsonRequestBehavior.AllowGet);
}
else
{
RedirectToAction("Login", "Admin");
return null;
}
}
catch (Exception ex)
{
return null;
}
}
вот мой класс ResearchModel
public Boolean SaveDataInDatabase(ResearchBL model, string userID,
HttpPostedFileBase ResearchFile, ref string Err)
{
var result = false;
using (ZUNew1Entities2 db = new ZUNew1Entities2())
{
if (model.ResearchID > 0)
{
if (!string.IsNullOrEmpty(model.ResearcherName)
&& !string.IsNullOrEmpty(model.ResearchName)
&& !string.IsNullOrEmpty(model.NameJournal)

&& !string.IsNullOrEmpty(model.VolumeNumber)
)
{
Research research =
db.Researches.SingleOrDefault(x => x.IsDeleted == false && x.ResearchID
==
model.ResearchID);
research.ResearchName = model.ResearchName;
research.ResearcherName =
model.ResearcherName;
research.NameJournal = model.NameJournal;
research.VolumeNumber = model.VolumeNumber;
research.ResearchContents =
model.ResearchContents;
string day = "01";
string cal = model.DateOfPublication + "-" +
day;
research.DateOfPublication =
Convert.ToDateTime(cal);
// Update Research File
****************************
string File;
string uploadFile =
"~/UploadFile/Researcher/Files/";
if (model.ResearchFile != null)
{
var fileName =
Path.GetFileName(ResearchFile.FileName);
string pathURL = uploadFile + userID +
"_" + DateTime.Now.Hour.ToString() + "_" +
DateTime.Now.Minute.ToString() +

DateTime.Now.Millisecond.ToString() +
".pdf";
var path =
Path.Combine(System.Web.HttpContext.Current.Server.MapPath(pathURL));
ResearchFile.SaveAs(path);
}
else
{
research.ResearchFile = null;
}
db.Entry(research).State =
EntityState.Modified;
db.SaveChanges();
result = true;
Err = "";
return true;
