Dictionaries map keys to values. For example, you might map an employee ID number to the object that represents the employee, or you might map a product ID to the object that represents the product. The .NET Framework includes the following dictionary classes:
1. Hashtable: A dictionary of name/value pairs that can be retrieved by name or index
2. SortedList: A dictionary that is sorted automatically by the key
3. StringDictionary: A hashtable with name/value pairs implemented as strongly typed strings
4.ListDictionary: A dictionary optimized for a small list of objects with fewer than 10 items
5. HybridDictionary: A dictionary that uses a ListDictionary for storage when the number of items is small and automatically switches to a Hashtable as the list grows
6. NameValueCollection: A dictionary of name/value pairs of strings that allows retrieval by name or index

The Dictionary type in the base class library is one of the most important ones you need to use for your C# programs. It is an implementation of a hashtable, which is an extremely efficient way to store keys for lookup. The Dictionary in .NET is well-designed, and this section shows lots of ways you can use it.
