How does Url.Action work Asp.net MVC?

Question

This is somewhat related to another question I\'ve asked but I figure why not ask it seperately.

If I were to place something like the following in a view

Answer 1

It will construct the path to the action, returning a url, not the results of executing the action.

The results will be:

<td>
   <img src='/User.mvc/DisplayImage?id=U00915441' alt="" />
</td>

Example code. assumes your user model has the image stored in a byte array. If you are using LINQ and the property is a Binary, then use the ToArray() method to convert it to a byte array. Note the attributes which will require that the user be logged in and using a GET request.

[Authorize]
[AcceptVerbs( HttpVerbs.Get )]
public ActionResult DisplayImage( string id )
{
     var user = ...get user from database...

     return File( user.Image, "image/jpeg" );
}

}
