What are Generic Collections in C#?

List<Employee> employeeList = new List<Employee>();

Employee emp1 = new Employee();
Employee emp2 = new Employee();

employeeList.Add(emp1);
employeeList.Add(emp2);

List<int> values = new List<int>();

values.Add(1);
values.Add(2);

int secondNumber = values[1]; // Yay! No casting or boxing required!

List<int> list = new List<int>();

List<Foo> fooList;

List<Employee> employeeList = new List<Employee>();
