Question

I want to retrieve an image from database and then send it to view and display it as thumbnail. Here is my code but It has some error and I can’t return the image properly.
I’m using ASP.Net MVC and aspx pages.

Controller :

public ActionResult showImg(int id)
{
   var imageData = from m in db.Products
                   where m.ShopId == 3
                   select Image.FromStream(new MemoryStream(m.Product_img.ToArray()));

   return new FileStreamResult(new System.IO.MemoryStream(imageData), "image/jpeg");
}

View :

<img src='<%= Url.Action("showImg", "image", new { id = ViewData["imageID"] } ) %>' />

It looks like you do not need to recreate the Image object in your linq statement, just return the stream and pass it your FileStreamResult:

var image = (from m in db.Products
             where m.ShopId == 3
             select m.Product_img).FirstOrDefault();

var stream = new MemoryStream(image.ToArray());

return new FileStreamResult(stream, "image/jpeg");
