Generics are the most powerful feature of C# 2.0. Generics allow you to define type-safe data structures, without committing to actual data types. This results in a significant performance boost and higher quality code, because you get to reuse data processing algorithms without duplicating type-specific code.
Generics provide a facility for creating data structures that are specialized to handle specific types when declaring a variable. Programmers define these parameterized types so that each variable of a particular generic type has the same internal algorithm but the types of data and method signatures can vary based on programmer preference.
