Question

I am trying to use this answer from an old post:
Display image from database in asp mvc
which is:

public class ImageController
{
    public ActionResult Show( int id )
    {
        var imageData = ...get bytes from database...

        return File( imageData, "image/jpg" );
    }
}

and I’m getting the following error:

‘System.IO.File’ is a ‘type’ but is used like a ‘variable’

This is what I’m using:

using System;
using System.IO;
using System.Drawing.Imaging;
using System.Web.Mvc;

What am I missing?

Answer 1

Make sure that your ImageController derives from Controller which is where the File method is defined:

public class ImageController: Controller
{
    public ActionResult Show( int id )
    {
        var imageData = ...get bytes from database...
        return File( imageData, "image/jpg" );
    }
}
