Question

I’m building a webapi and I have strange problem.

When I do something like this

List<Content> items = new List<Content>();

And than i add items to it

items.Add(new Content());

And than I invoke url localhost/api/Content/Get I’ll get a nice xml with my items
But when I do something like this

public IEnumerable<Content> Get()
{
    List<Content> population = new List<Content>();
    Content[] test = new Content[5];

    var tmp = from c in db.Content select c;
    using (IEnumerator<Content> enumerator = tmp.GetEnumerator())
    {
        while (enumerator.MoveNext())
        {
            Content ctmp = (Content)enumerator.Current;
            population.Add(ctmp);
        }
    }
    return population;
}

And I invoke same url I get blank (white) page. Same think when I’ll return the tmp variable.

Update:

thanks for help. Main question is still standing. Why normal List is returned correctly and List created from db isn`t. Making a copy from DataProxies.Content to COntent isn’t the solution that I’ve dreamed off and as Jon noticed it’s a bit odd.

None of samples with db.Content.ToList() helped :/ I’m confuesed

Answer 1

I found the solution. At least I think I did

I use

db.Configuration.ProxyCreationEnabled = false;

Than I get normal objects not proxy dynamic entities

About your question Jon. How am I exposing that method ? There is not much to tell. I`ve created ApiController from template and just edited the method

    public class ContentController : ApiController
{
    private signsEntities db = new signsEntities();

    // GET api/content
    public IEnumerable<Content> Get()
    {
        db.Configuration.ProxyCreationEnabled = false;
        Content[] test = this.db.Content.ToArray<Content>();
        return test;
    }
}

This is whole class. Not much as you can see 🙂
