Answer 2

C#中的list可以当做数组使用，而且无需定义长度，完全是动态的
class Person
{
public string Name { get; set; }
public string Address { get; set; }
}
static void Main(string[] args)
{
List<Person> people = new List<Person>();
people.Add(new Person()
{
Name = "kaka",
Address = "22,2nd cross,bangalore"
});
//no casting needed
Person p = people[0];
}
