Answer 1

I think something like this could work:

yourCollection.Where(x => 
    DateTime.Compare(x.DateTimeProperty, DateTime.Today.AddMonths(-3)) >= 0);

Answer 2

var minDate = DateTime.Now.AddMonths(-3);

from x in datatable
where x.datevalue> minDate
select x;

Answer 3

from x in datatable
where x.datevalue> DateTime.Now.AddMonths(-3) 
orderby x.id ascending
select x;
