Question

Hi all I am working on MVC4. I have uploaded a single image file, it is saved in the destination folder, but now I need a loop so that image the is saved more than 100 times.

Here is my code,

This is my controller:

     [HttpPost]

        public ActionResult Uploading(ImageModel model)
        {
            if (ModelState.IsValid)
            {     
                string fileName = Guid.NewGuid().ToString();
                string serverPath = Server.MapPath("~");
                string imagesPath = serverPath + "Content\\Images\\";
                string thumsise = Path.Combine(imagesPath, "Thumb" + fileName);

                ImageModel.ResizeAndSave(thumsise, fileName, model.ImageUploaded.InputStream, 80, true);

            }
            return View("Upload",model);
        }

and this is my index page:

@using (Html.BeginForm("Uploading", "Upload", FormMethod.Post, new { enctype = "multipart/form-data" }))
     {
         <input type="file" name="ImageUploaded" id="btnUpload" multiple="multiple" accept="image/*"  />
     <button type="submit"  id="Upload">Upload</button>
         <br />
}

Could you please help me to do this? Thanks in advance.

How about writing a for loop:

[HttpPost]
public ActionResult Uploading(ImageModel model)
{
    if (ModelState.IsValid)
    {     
        string imagesPath = Server.MapPath("~/Content/Images");
        string fileName = Guid.NewGuid().ToString();
        for (var i = 1; i <= 100; i++) 
        {
            string thumsise = Path.Combine(
                imagesPath, 
                string.Format("Thumb{0}_{1}", fileName, i)
            );
            ImageModel.ResizeAndSave(thumsise, fileName, model.ImageUploaded.InputStream, 80, true);
        }
        return View("Upload",model);
    }
}

This will create 100 images in the ~/Content/Images folder by prefixing the Guid with Thumb and by suffixing it with the index of the loop.
