Hi I am trying to query my Mongo Database by using a list of Facebook ID's as the parameter in order to return the list of users with corresponding accounts. The method works fine in the Unity Editor however when I run it on iOS I get a constructor error (I have set a blank default constructor in order to solve the issue however it still doesn't work)
Initial Method
public void FetchData() { //data = Mongo.Instance.players.FindAll().ToList(); if (FB.IsLoggedIn) { FB.API("me/friends", HttpMethod.GET, FriendsHighscoreHndlr); } } Callback Method
public void FriendsHighscoreHndlr (IGraphResult FBresult){ var dict = Json.Deserialize(FBresult.ToString()) as Dictionary<string,object>; var friendList = new List<object>(); friendList = (List<object>)(dict["data"]); int _friendCount = friendList.Count; Debug.Log("Found friends on FB, _friendCount ... " +_friendCount); List<string> friendIDsFromFB = new List<string>(); for (int i=0; i<_friendCount; i++) { string friendFBID = getDataValueForKey( (Dictionary<string,object>)(friendList[i]), "id"); string friendName = getDataValueForKey( (Dictionary<string,object>)(friendList[i]), "name"); Debug.Log( i +"/" +_friendCount +" " +friendFBID +" " +friendName); friendIDsFromFB.Add(friendFBID); } //friendIDsFromFB.Add(AccessToken.CurrentAccessToken.UserId); var query = Query.In("facebookID", BsonArray.Create(friendIDsFromFB)); //Debug.Log(query); data = Mongo.Instance.players.Find(query).ToList(); } Data Value for Key Method
private string getDataValueForKey(Dictionary<string, object> dict, string key) { object objectForKey; if (dict.TryGetValue(key, out objectForKey)) { return (string)objectForKey; } else { return ""; } } Return Query Result
{ "_id" : ObjectId("XXXXXX"), "facebookID" : "XXXXXXXXXXXXXX", "name" : "John Doe", "highScore" : 40501 } 1 Answers

Have you tried using a filter from Mongo's .NET drivers?
I would suggest trying something like the example below. (Note: this event is being fired on a pre-defined object which is being defined as a collection.)
var filter = Builders<Object>.Filter.Eq(obj => obj.attribute, List<IDs>);
