Collection Vs Hashtable (VB.NET )

Referring to System.Collections.Hashtable and Microsoft.Visualbasic.Collection
  • Collection - non case-sensitive string pattern (that is why it supports string as key)
  • Hashtable - specific index key (that is why it supports object as key and not string as key)
  • Hashtable - for accurate and fast return of item using the key
  • Collection - for lesser accurate (based on non-case sensitive string pattern) and slower return of item using the key.
  • Hashtable - used for lookup purposes with distinctive key searching facility.
  • Collection - used for storing a growing collection of items with non case-sensitive string pattern (key) searching facility.
