Entity Framework - Include 3 sublevels of properties
I'm using EF6 Code-First.
I have four-leveled entities with the following hierarchy:
Express(top level)
-> Constant(1st sublevel)
-> Event(also 1st sublevel)
-> Parameter(2nd sublevel)
-> Value(3rd sublevel)
I can obtain 2 sublevels via
db.Expresses.Include(ex=>ex.Constants).Include(ex=>ex.Events.Select(ev=>ev.Parameters));
But how can I include third sublevel (Value) in that query?

db.Expresses.Include(ex => ex.Constants)
.Include(ex => ex.Events.Select(ev => ev.Parameters.Select(par => par.Value)));
Please ensure using System.Data.Entity namespace to get the overrides of Include method.
See this link for more examples.
Oh, that was so easy :) Thx.

An alternative is to use strings
db.Expresses.Include("Constants")
.Include("Events.Parameters.Values")
