I'm trying to create a generic function to get a Predicate

private IPredicateExpression GetPredicate(IEntityFields  Fields, Int SomeID) 
{

     IPredicateExpression select = new PredicateExpression();
     select.AddWithAnd(Fields["ID"] == SomeID); 
     etc....
    return select;
}

But of course fails. How can I add a predicate with a generic IEntityFields?

select.AddWithAnd(((EntityField)Fields["ID"]) == SomeID);

or if you're using adapter, cast to EntityField2 You can also use new FieldCompareValuePredicate(... )

THe interfaces won't work, as operators can't be defined on interfaces.

Along the same line, how do I set a Field value like this:

private void SetStuff(IEntityFields Fields, IEntityCollection Collection) { Collection.GetMulti(some predicate);

         foreach (EntityBase entity in Collection)
         {
             entity.IsNew = true;
        **   entity.Fields["A name of a field"] = a value;**  -- FAILS of course
         }

}

Found it:

entity.SetNewFieldValue
