Question

I have a database where I have saved image

How can I display the image ?
Now I display it like this

    <img alt="@album.Room_number" src="@album.ImageData" />

But I get this:

Answer 1

You could use the Data URI scheme if your client browser supports it:

<img alt="@album.Room_number" src="data:image/jpeg;base64,@Convert.ToBase64String(album.ImageData)" />

If the browser doesn’t support it you will have to create a controller action that queries the database and streams the image to the response:

public ActionResult Image(int id)
{
    byte[] imageData = ... go and fetch the corresponding image data from the database
    return File(imageData, "image/jpeg");
}

and then:

<img alt="@album.Room_number" src="@Url.Action("Image", new { id = album.ImageId })" />

Of course in this case you should not fetch the ImageData property within the initial request to avoid to unnecessary query it while not using it anymore in the view.
