I finally found the solution for it. ;)

        if (model.File != null && model.File.ContentLength > 0)
        {
            Byte[] destination1 = new Byte[model.File.ContentLength];
            model.File.InputStream.Position = 0;
            model.File.InputStream.Read(destination1, 0, model.File.ContentLength);
            model.BankSlip = destination1;
            Session["info.file"]= model.File;//storing session.
        }
        else
        {
            //retrieving session
            var myImg1 = Session["info.file"] as HttpPostedFileBase;
            model.File = myImg1;
            Byte[] data=new Byte[myImg1.ContentLength];
            myImg1.InputStream.Position = 0;
            myImg1.InputStream.Read(data, 0, myImg1.ContentLength);
            model.BankSlip = data;
        }
        }
        catch (Exception ex)
        {                   
            DepositControllerLog.ErrorException("DepositController - LocalBank(Post) - AddAttachment(refreshed) - ", ex);
        }
