I am using this block of code to find documents in a collection.
Can I get the count of documents from a cursor ?



Or is there a way I can get only the count of documents by giving the findoptions ? 



using (var cursor = await collection.FindAsync(filterExpression, new FindOptions<BsonDocument, BsonDocument>

{

    Projection = projectionDef,

    Skip = findOptions.Skip,

    Limit = findOptions.Limit,

    Sort = sortExpression

}, cancellationToken).ConfigureAwait(false))

{

    while (await cursor.MoveNextAsync().ConfigureAwait(false))

    {

        foreach (var document in cursor.Current)

        {

            var docObject = BsonSerializer.Deserialize<object>(document);

            var x = JObject.FromObject(docObject);

            result.Add(x);

        }

    }

}

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.



















  • If you have a "new question" then ask a new question just like the box there is telling you to do. Please don't change questions from the basic thing they originally asked, especially when marked to an existing duplicate or answered directly. New Question, new post. That's how it works here. Please follow the guidelines everyone else does.
