Ch 14: Try it Out p. 510 - error 'PlanetWroxModel.Picture' is a 'type'

Here's an error I couldn't find listed elsewhere on the forums.

After completing all the instructions on p. 505-511, (actually even when completing the code on step 12), I get this error:

'PlanetWroxModel.Picture' is a 'type' but is used like a 'variable'

My code looks like Imar's in the book:

Code:

    

using PlanetWroxModel;

...

protected void EntityDataSource1_Inserting(object sender, EntityDataSourceChangingEventArgs e)
    {
        int photoAlbumId = Convert.ToInt32(Request.QueryString.Get("PhotoAlbumId"));
        Picture myPicture = (Picture).e.Entity;
        myPicture.PhotoAlbumId = photoAlbumId;
    }

The line in bold red immediately returns an error, as well as an error at runtime. What did I do wrong?

Hi Jay,

There's one dot too many in this code:

Code:

 
Picture myPicture = (Picture).e.Entity; //Extra . after (Picture)

It should be:

Code:

 
Picture myPicture = (Picture) e.Entity;

By adding the dot, you indeed tell the compiler that (Picture) is a variable with an e property.

Hope this helps,

Imar

Ha, thanks Imar! More than one set of eyes is always useful!

Best,
