How to I Start with C# Generics?

[Anonieko Ramos]

The logical thing to do is to try it yourself.

See this example:
-----------------------------------------------------------

using System;
using System.Collections.Generic;

namespace Tests
{

public class Employee
{
int id;
string name;

public Employee(int anId, string aName)
{
this.id = anId;
this.name = aName;
}

public int Id
{
get { return this.id; }
}

public string Name
{
get { return this.name; }

set { this.name = value; }
}
}

}



namespace Tests
{

public class GenericReferenceArrayListTest {

static void Main()
{
DateTime start = DateTime.Now;

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

Employee emp = new Employee(101, "Smith, Joan");


for (int i = 0; i < 1000000; i++)
{
employees.Add(emp);
}

foreach (Employee e in employees)
{
Employee currentEmployee = e;
}

DateTime finish = DateTime.Now;

System.Console.WriteLine(String.Format("Elapsed time: {0}",
finish.Subtract(start)));
}

}

}
