Dictionary and Hash table are collection of data structure to hold data as key/value pairs.
Dictionary is generic type, hash table is not
We can't use dictionary with web services.
In .NET hash table is thread safe for use by multiple reader thread and a single writing thread, while in dictionary public static members are thread safe, but any instance members are not guaranteed to be thread safe.

Answer / mehdi

Dictionary is a generic type, Hashtable is not. That means
you get type safety with Dictionary, because you can't
insert any random object into it, and you don't have to
cast the values you take out.

Answer / sunil kumar

Dictionary is a generic type, Hashtable is not. Now what that
means.You get type safety with Dictionary, because you can't
insert any random object into it, and you don't have to cast
the values you take out.
And also generic collections are a lot faster as there's no
boxing/unboxing
Again Hashtable also have to box/unbox, which may have memory
consumption as well as performance penalties.
