How to get one property from Ilist<T> where other properties are True

I'm trying to select ID from an Ilist<T> where 2 boolean properties are equal true 

myList.Select(t => t.IsValid && t.IsBalance).Distinct().ToList();

but if I want to return and select only the t.ID where t.IsValid and t.IsBalance how to do so ? I couldn't find an example

Thank you

Use Where for the filtering and Select for projection:

myList.Where(t => t.IsValid && t.IsBalance).Select(t => t.ID).Distinct().ToList();

You can also use query syntax:

var result = (from t in myList
              where t.IsValue && t.IsBalance
              select t.ID).Distinct().ToList();
