Question

How i can push an item in an Array?
I see that i can insert only basic value (String, Int32, Int64, Boolean) but i can’t insert into an array an INSTANCE of custom class.

//in this way, it work:
var myPlayer = new i_Player();
this.mongo_collection.FindAndModify(
Query.EQ("_id",ID),
SortBy.Ascending("_id"),
Update.PushWrapped<i_Player>("_player", myPlayer),
true
);

// in this way, don't work because i_Player is not an BsonValue but is my CLASS!
var myPlayer = new i_Player();
this.mongo_collection.FindAndModify(
Query.EQ("_id",ID),
SortBy.Ascending("_id"),
Update.Push("_player", myPlayer),
true
);

PushWrapped coming with driver 1.0 (seems) and simply convert your class to BsonDocument:

Update.PushWrapped<i_Player>("_player", myPlayer);

In case if you using Update.Push you need to do it manually:

Update.Push("_player", myPlayer.ToBsonDocument()); 

I am using ToBsonDocument() to convert some class object to BsonValue.

So, just choose what do you like more..
