Find an specific element in a MongoDB document from C# -

i trying access mongodb c# asp.net application.

let's assume, i've document below-

{     "_id" : objectid("546c776b3e23f5f2ebdd3b03"),     "name" : "test",     "values" : [          {             "name" : "one",             "value" : 1         },          {             "name" : "two",             "value" : 2,             "parameters": [{"type": "type a"}, {"type": "type b"}]         }     ] } 

please note that, _id , name elements fixed; other elements dynamically created user both key , value defined user.

now, search element type value type a. how can mongodb c# driver?

you can use code:

var query = query.eq("values.parameters.type", "type a"); var items = collection.find(query).tolist(); 

if data has structure use this:

var items = collection.findas<item>(query).tolist(); 

edit: dynaically search way comes mind full-text-search:

step1: define full text-search on fields via db.test.ensureindex({"$**" : "text"});

step2: search query db.test.find( { $text: { $search: "type a" } } )

if answer, c# code should easy.
