Inheritance in MongoDb: how to request instances of defined type

Question

This is how I used to utilize inheritance in Entity Framework (POCO):

ctx.Animals // base class instances (all instances)
ctx.Animals.OfType  // inher         


        

Answer 1

If the only concern is hardcoding class name, you can do something like this:

collection = db.GetCollection("Animals");
var query = Query.EQ("_t", typeof(Cat).Name);
var cursor = collection.Find(query);
