The Difference between Hashtable and Dictionary is below,
| Hashtable | Dictionary |
|---|---|
| Hashtable is included in the System. Collections namespace. | Dictionary is included in the System.Collections.Generic namespace. |
| Hashtable is a loosely typed (non-generic) collection, this means it stores key-value pairs of any data type. | Dictionary is a generic collection. So it can store key-value pairs of specific data types. |
| Hashtable is thread-safe. | Only public static members are thread-safe in Dictionary. |
| Hashtable returns null if we try to find a key which does not exist. | Dictionary throws an exception if we try to find a key that does not exist. |
| Data retrieval is slower than dictionary because of boxing-unboxing. | Data retrieval is faster than Hashtable. |
I hope, this will help you.
