.net - Making a string property ObjectId in MongoDB with C# -

-

i started mongodb. using c# drivers. c# class looks this:

 [bsonrepresentation(bsontype.objectid)]         public string id { get; set; }         public string userid { get; set; }         public list<string> filters { get; set; }

with class able save , fetch records in mongodb.

what want:- instead of creating separate property hold id (in case id property), want make userid property objectid.

please note, supplying userid unique string value. possible achieve mongodb?

sure possible.

just put [bsonid] on userid prop , delete id property
