Question

How to upload multiple images? 

Hi, I want to upload multiple images in the database base, I select the multiple-image and then upload button but insert in the database only 1 image, any expert can you tell me where I am wrong.

 

 Image Model

public partial class Image
    {
        public int imgID { get; set; }
        public string ImgPath { get; set; }
        public long ProdID { get; set; }

        public virtual Product Product { get; set; }
    }

 Controler

public ActionResult AddNewProducts(ProductViewModel prod, List file)
       {
           try
           {
               List PTlist = _IproductType.PTList();
               ViewBag.Ptlist = new SelectList(PTlist, "PType_ID", "P_Name");

               //Product Color List
               List pColorList = _IProductColor.PColorlist();
               ViewBag.pColor_List = new SelectList(pColorList, "C_ID", "C_Name_OR_Code");

               List pSizeList = _ISize.pSizeList();
               ViewBag.pSizeLists = new SelectList(pSizeList, "S_ID", "S_Size");


           string PathDB = string.Empty;
               Image img = new Image();
               foreach (HttpPostedFileBase files in file)
               {
                   string filename = Path.GetFileName(files.FileName);
                   string _filename = DateTime.Now.ToString("yymmssff") + filename;
                   string extension = Path.GetExtension(files.FileName);
                   string path = Path.Combine(Server.MapPath("~/Upload/"), _filename);
                   PathDB = "~/Upload/" + _filename;
                   if (extension.ToLower() == ".jpeg" || extension.ToLower() == ".jpg" || extension.ToLower() == ".png")
                   {
                       if (files.ContentLength <= 1000000)
                       {
                           img = new Image();
                           img.imgID = prod.ImgID;
                           img.ImgPath = PathDB;
                           img.ProdID = prod.ProductID;

                       }
                       else
                           ViewBag.sizemsg = "Size Limit accessed ";
                   }
                   else
                       ViewBag.fileformat = "File is not Format is not Correct";

               }
}
}
