What is Generics Classes? Sample code for Generic Classes

Generic classes are available in System.Collections.Generic namespace.
public class List

Among the methods of that class is this one:
public Add(T item)

T is the placeholder for the type that an instance of the generic class
System.Collections.Generic.List will store.

In defining an instance of the generic class, one
specifies the actual type that the instance will store:

List myListOfStrings = new List();

Then one can use the Add() method of the generic class instance like so:

myListOfStrings.Add("Hello, World");

A generic interface may be implemented by a generic type or a nongeneric type.

public interface IMyGenericInterface
void MyMethod();

A sample code to understand Generic Class.

public class Printer
public void Print(T argument)
if(typeof(T) == typeof(string))
static void Main(string[] arguments)
Printer printer = new Printer();
printer.Print("Hello, World");
