MongoDb Query using C# for date time -


i working on mongodb using c# drivers. want query mongodb database find out row has eventdate greater 13 months todays date.

my mongodb has structure similar below:

eventdate of datatype : datetime

{    "_id" : objectid("525239e3e9374f1c3ce4123b"),    "rowid" : 41133552,    "eventdate" : isodate("2013-08-19t00:00:28z"),    "product" : "supporttool",    "language" : "en",    "guid" : "67cd73d4-36bc-4c9f-9a4c-144b38d4e928", }

please can me out mongocollection data event date older 13 months.

there's more 1 way it, 1 linq extension method syntax:

mongodatabase db = yourmongodatabaseobject; var cursor = db.getcollection<yourclass>("yourclass").find(    query<yourclass>.lt(p => p.eventdate, datetime.utcnow.addmonths(-13));

this return cursor documents in "yourclass" collection have an eventdate less 13 months ago , deserialize them instances of yourclass.
