Your method returns a HashTable() instead of a single HashTable. Change it to:

Public Shared Function LstItemsAsHT() As Hashtable

Apart form that, why do you still use a Hashtable at all if you can use a strong typed Dictionary(Of Int32, String)? Also, the result.ToList() is not needed. You can enumerate the sequence immediately without creating a new list first.
