• You can use generic types/classes to maximize code reuse, type safety, and performance.
• The most common use of generics is to create collection classes.

public class Student
{
  private string name = "satish";
  private Int16 RollNo = 12;

  public void displayStudent()
  {
    Console.WriteLine(name);
    Console.WriteLine(RollNo);
    Console.ReadLine();
  }
}

class Program
{
  static void Main(string[] args)
  {
    List<Student> students = new List<Student>();
    students.Add(new Student());
    foreach(var std in students){
      std.displayStudents();
    }
  }
}
