I hope this helps . The count method can now be found in MongoCollection:
code :
int count = collection.count();
int count = collection.count(criteria);

hop of those help? There have been several related bugfixes made in 1.2.11-dev. I can reproduce the crash using pecl/mongo v1.2.10, but not with the current v1.2.11-dev.
How to get distinct values by using c# MongoCursor?

How to get distinct values by using c# MongoCursor?

Hope this helps I have accomplished the desired result using runCommand approach. I have a collection called "capped". In it are records with field called "x". I have inserted different values into the collection, among them, multiple values of 27. The Javascript statement below says "I want distinct values on collection capped where the distinc key is column called 'x', and I am querying for values where x is 27".
In Javascript, it looks like this:
code :
      CommandDocument distinctCmd = new CommandDocument{
          {"distinct", "capped"},
          {"query", new BsonDocument("x", 27)},
          {"key", "x"}            };
      CommandResult r = database.RunCommand(distinctCmd);

Does that help i am developing RESTful API's using mongodb & PHP. I have used find function to retrive records based on condition. Find function returns me mongocursor which i have to iterate through foreach loop to access data , Simply you can do the following
code :
$teamsCount = $mongoDb2->find(array('team_maker_id' => (string)$userid))->count();

will help you I need a var (res in the following) to accept the answer of a find(), i.e. MongoCursor, because I have to have access to my var inside if-conditions (see below).
code :
var res: MongoCursor = _
val res =  if ("condition_1" == field_1)) {
             query += "field" -> "t"
             if ("condition_2" == "field_2")) {
               collection.find(q).sort("basic_field" -> 1)
             } else if ("condition_2" == "field_2")) {
               collection.find(q).sort("important_field" -> -1).limit(101)
             }
           }

hop of those help? That's because MongoCursor class does not have method called toArray. Here is a list of all available methods- MongoCursor.
You should use iterator_to_array() as in Example #1 in manual:
