mongodb - How to store an array of string in c#? -

either

hashset<string> aaa { get; set; } 

or

list<string> aaa { get; set; } 

or

string[] aaa { get; set; } 

also store as:

"aaa": {      "0": "bbb",      "1": "ccc"  }, 

can't store as

"aaa": ["bbb", "ccc"]  

?

the following code latest 10gen drivers produces document in format you're looking for:

public class mydocument {     public int id { get; set; }     public string[] aaa { get; set; } }  class program {     private static void main(string[] args)     {         var client = new mongoclient("mongodb://localhost");         var server = client.getserver();         var db = server.getdatabase("temp");         var coll = db.getcollection("mydocuments");         var mydoc = new mydocument             {                 id = 1,                 aaa = new[] {"bbb", "ccc"}             };         coll.save(mydoc);     } } 

here resulting document:

/* 0 */ {     "_id" : 1,     "aaa" : [          "bbb",          "ccc"     ] } 

ilist , list work. have custom bson serialization annotations? have custom class maps?
