C # type Parameters Study

Type Parameters

A class definition may specify a set of type parameters by following the class name with Angle brackets enclosing a list of type parameter names. the type parameters can the be used in the body of the class declarations to define the members of the class. in the following example, the type parameters of pair are tfirst and tsecond:

Public class pair <tfirst, tsecond>
{
Public tfirst first;

Public tsecond second;
}

A class type that is declared to take type parameters is called a generic class type. struct, interface and delegate types can also be generic.

When the generic class is used, type arguments must be provided for each of the type parameters:

Pair <int, string> pair = new pair <int, string> {First = 1, second = "two "};
Int I = pair. First; // tfirst is int
String S = pair. Second; // tsecond is string

A generic type with type arguments provided, like pair <int, string> abve, is called a constructed type
