MongoDB c# Update.PushWrapped，如何使用？
我如何将一个项目推送到数组中？ 我发现我只能插入基本值（String、Int32、Int64、Boolean），但我无法将自定义类的实例插入数组。
//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
);
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与驱动程序 1.0 一起提供（似乎），只需将您的类转换为BsonDocument：如果您使用
Update.Push，您需要这样做手动：我正在使用
ToBsonDocument()将某些类对象转换为BsonValue。所以，就选择你更喜欢什么吧..
PushWrappedcoming with driver 1.0 (seems) and simply convert your class toBsonDocument:In case if you using
Update.Pushyou need to do it manually:I am using
ToBsonDocument()to convert some class object toBsonValue.So, just choose what do you like more..
