C#如何使用List类实现动态变长数组

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];
}
