IComparable and multiple sorting

[Steph]

Hello,
i dot not manage to write the code to sort a array on multiple columns.
ArrayList people = new ArrayList();
people.Add(new Person("John", "Doe", 76));
people.Add(new Person("Matt", "Dire", 80));
people.Add(new Person("Matew", "Vinz", 75));
people.Add(new Person("Arlett", "Blaste", 84));

so, i want now sorting by Name, Surname and Year :

Array.Sort(people,Person.sortNameSurnameYearAscend ing());// Méthode devant
retourner l'objet IComparer pour l'aide de tri.
public static IComparer sortNameSurnameYearAscending()
{
return (IComparer) new sortNameSurnameYearAscendingHelper();
}private class sortNameSurnameYearAscendingHelper : IComparer
{

int IComparer.Compare(object a, object b)
{ Person a1 = (Person)a; Person b1 = (Person)b;
?? what do here...
//return 1;
}

}
