Is it really so simply? Use Take:

 internal List<items> test(List<long> ids)
 {
     return classA.GetValue(ids.Take(2).ToList()).Take(2).ToList();
 }

I dont know why you need to take 2 from the ids and pass these to GetValue as mentioned.

Using Linq,

var cids = ids.Take(2).ToList();

That's probably the simplest. Not much more to add... unless I gravely misunderstood the question.
