C# MongoDB multiple similar records -

i have started using mongodb , have question... how do following:

var testrec = new testclass {   name = "john",   address = "10 here st",   recordtype = "a" };  db.save(testrec);  testrec.recordtype = "b"; db.save(testrec); 

i want second save save new document there should 2 documents same details except recordtype.

what seems happen overrides first document second.

can please let me know.

thanks dean

you need new id , insert instead of updating. here complete example:

using system; using mongodb.bson; using mongodb.driver;  namespace mongotest {     class testclass{         public string name;         public string address;         public string recordtype;         public objectid id;     }      class mainclass     {         public static void main (string[] args)         {             var connectionstring = "mongodb://localhost";             var client = new mongoclient(connectionstring);             var server = client.getserver();             var db = server.getdatabase("test");             var collection = db.getcollection("test");              var testrec = new testclass             {                 name = "john",                 address = "10 here st",                 recordtype = "a",                 id = new objectid()             };              collection.save(testrec);             testrec.id = new objectid();             testrec.recordtype = "b";             collection.save(testrec);             testrec.id = new objectid();             testrec.recordtype = "c";             collection.save(testrec);          }     } }
