Dictionary provides generic types
allows to create dictionary of any type. Where as HashTable will store values in
the form of object. So, while using a collection of primitive types such as
integer, hashtable will have additional cost of boxing and unboxing, where as
dictionary is generic, it will not have additional cost of boxing and
unboxing.
If the collection if of type int,datetime,float etc, Dictionary provides
better performance than hashtable.
If the collection is of type custom object, Both will provide same
performance.

There is generic version available for Dictionary in .net.
Hashtable is a collection of key/value pairs that are organized based on the hash code of the key.
