Using a .NET MVC Controller Action as the Source for an HTML <img>

Question

I'm trying to display the picture associated with a user in my database (the picture field's data type is image) on a page - unfortunately the code below fails to do that.

HTML

<img src="/User/Picture/1" />

Controller Action

public byte[] Picture(int id){
    UserRepository r = new UserRepository();
    return r.Single(id).logo.ToArray();
}

Answer 1

PROBLEM SOLVED

Apologies, I didn't read up enough on this!

All that needed to be done was make the Controller Action return FileContentResult

public FileContentResult Picture(int id)
{
    UserRepository r = new UserRepository();   
    return new FileContentResult(r.Single(id).logo.ToArray(), "image/jpeg");
}

Answer 2

This question has a lot of useful answers. You probably need the FileContentResult-related answers.

In short, you need to return appropriate ActionResult, and not just array of bytes.
