Question

My ApiController is supposed to return data:

// GET api/profile
public IEnumerable<HubBasicProfile> GetProjectProfiles()
{
    IEnumerable<HubBasicProfile> res = _bpss.GetAllBasicProfiles();
    return res;
}

When I debug and inspect res before it is returned, it has data for 91 HubBasicProfile objects.

However, when the data is returned, I see 91 {}, empty objects. No data at all.

Anybody any clue why this might be?

Thanks
Eric

Answer 1

call the ToList() method. So deferred execution won’t happen.

public IEnumerable<HubBasicProfile> GetProjectProfiles()
{
    IEnumerable<HubBasicProfile> res = _bpss.GetAllBasicProfiles();
    return res.ToList();
}

Deferred execution means that the evaluation of an expression is
delayed until its realized value is actually required
collection.

EDIT : As per the comment

If you are serializing these items, You need to make sure your class is marked as serializable / has the [DataMember]/ [DataContract] Attributes.
