Projection in Where Clause Query of a Embedded document in MongoDB Collection using C#

Question

Filter the Collection in DB instead of Memory

I\'m having a Model Class, Save it in a MongoDB Collection then Query the same as per my expec

Answer 1

EDIT

Added projection - so selected array contains only documents where IsLive==true

I think it is easier to use typed queries as c# is strongly typed language. I used ElemMatch as this is designed to scan an array and looks for a matching element.

var filterDef = new FilterDefinitionBuilder();
var filter = filterDef.Eq(x => x.IsLive, true);

var projectDef = new ProjectionDefinitionBuilder();
var projection = projectDef.ElemMatch("EmpMobile", "{IsLive:true}");            

var empList = collectionEmpInfo.Find(filter).Project(projection).ToList();
