C# - Generics
Generics allow you to delay the specification of the data type of programming elements in a class or a method, until it is actually used in the program. In other words, generics allow you to write a class or method that can work with any data type. You write the specifications for the class or the method, with substitute parameters for data types. When the compiler encounters a constructor for the class or a function call for the method, it generates code to handle the specific data type. A simple example would help understanding the concept: using System; using System.Collections.Generic; namespace GenericApplication { public class MyGenericArray<T> { private T[] array; public MyGenericArray(int size) { array = new T[size + 1]; } public T getItem(int index) { return array[index]; } public void setItem(int index, T value) { array[index] = valu
