Session item always null in asp.net mvc3

Question

The function to upload image:

        [HttpPost]
        public String UploadSingle(HttpPostedFileBase imageFile)
    {
        try
        {
            String fileSavePath = Server.MapPath("~/Content/Temp/" +
               imageFile.FileName);
            imageFile.SaveAs(fileSavePath);

            List<String> uploadedFile = (List<String>)HttpContext.Session["UploadedFiles"];
            if (uploadedFile == null)
            {
                uploadedFile = new List<string>();
            }

            uploadedFile.Add(fileSavePath);
            HttpContext.Session["UploadedFiles"] = uploadedFile;
            return "Success";
        }
        catch (Exception e)
        {
            return "Error";
        }
    }

This function work okay, the image is uploaded. But when i try to see the uploaded images.

 public String UploadResult()
    {
        List<String> uploadedFile = (List<String>)HttpContext.Session["UploadedFiles"];

        return uploadedFile.Count + "";
    }

When i debug, the HttpContext.Session["UploadedFiles"] always return null. Please give me some help.

Use HttpContext.Current.Session["UploadedFiles"] instead of HttpContext.Session["UploadedFiles"]

HttpContext.Current.Session simply returns null if there is no session available.
