Return a blob image error

Hello guys,

I created a controller and a view, to fetch data from my database an image, which is in blob format. However, the image is not loaded in the view (I call a method to call this view).

I have the controller Image (with the GetImage method), the ReadyDrive controller and the ReadyDelivery view. Within the ReadyDate view, I pass the parameter to get the ID in the GetImage method.

Controller Imagem:

public ActionResult Index()
{
return View();
}
public ActionResult GetImagem(int id)
{
Entities1 tabela = new Entities1();
byte[] BlobImg = tabela.DATABINARY.Where(p => p.ID.Equals(id)).Select(p => p.DATA).FirstOrDefault();
return File(BlobImg, "image/png");
}

Controller ProntaEntrega

public ActionResult Index(int? reduzido=null)
{
Entities1 Estoque = new Entities1();
List ProntaE = (from a in Estoque.V500_ESTOQUE_PE_WEB select a).OrderByDescending(x => x.TOTAL_KG_PE).ToList()
.Where(x => reduzido != null ? x.COD_REDUZIDO.Equals(reduzido) : true).ToList();
return View(ProntaE);
}

View ProntaEntrega (a piece of that):

@foreach (var item in Model)
{
class="text-left" width="30%">
@Html.DisplayFor(d => item.COD_REDUZIDO)
class="text-left">
@Html.DisplayFor(d => item.DESC_ARTIGO)
class="text-right">
@Html.DisplayFor(d => item.TOTAL_KG_PE)
"@Url.Action("GetImage", "Imagem", new { id = @item.IDBLOB})" width=50 />
}

But the images do not load on view.

Any help me?

Thanks!

Do you have an example? How can I do?

The img src tag needs a URL i.e. the fully qualified address in plain text which you can type in any browser's address bar then you should be able to see that image in a browser.

but I see here you are returning a file object which won't work.

you need to have a virtual directory under your project folder or anywhere else where your site is deployed on IIS, then you have to write this file in that directory and return the full URL, then it will work.
