Generics, or parameterized types, or parametric polymorphism is a .NET 2.0 feature supported by C# and Visual Basic. Unlike C++ templates, .NET parameterized types are instantiated at runtime rather than by the compiler; hence they can be cross-language whereas C++ templates cannot.
C# (/ ˌ s iː ˈ ʃ ɑːr p / see SHARP) [b] is a general-purpose high-level programming language supporting multiple paradigms.C# encompasses static typing, [16]: 4 strong typing, lexically scoped, imperative, declarative, functional, generic, [16]: 22 object-oriented (class-based), and component-oriented programming disciplines.
C# 3.0 introduced type inference, allowing the type specifier of a variable declaration to be replaced by the keyword var, if its actual type can be statically determined from the initializer. This reduces repetition, especially for types with multiple generic type-parameters , and adheres more closely to the DRY principle.
A generic unit is a package or a subprogram that takes one or more generic formal parameters. [18] A generic formal parameter is a value, a variable, a constant, a type, a subprogram, or even an instance of another, designated, generic unit. For generic formal types, the syntax distinguishes between discrete, floating-point, fixed-point, access ...
Type information about C# generic types is fully preserved at runtime, and allows full reflection support and instantiation of generic types. Reflection cannot be used to construct new generic realizations. During compilation extra code (typecasts) are injected into the client code of generics. This precludes creating new realizations later.

Generic programming – uses algorithms written in terms of to-be-specified-later types that are then instantiated as needed for specific types provided as parameters; Imperative programming – explicit statements that change a program state; Logic programming – uses explicit mathematical logic for programming
