I have list of objects that has a CountyId property.  I want to filter that list, via Linq, by another list, EligibleCounties

IList<long> eligibleCounties = new List<long>{1, 2, 3};

class MyClass
  public Name { get; set; }
  public CountyId { get; set; }

IList<MyClass> myList...

var subList = MyList.Where(x => x.CountyId  "in eligibleCounties")  ???

Thanks in advance!!!
