创建一个集合类People，它是下述Person类的集合，该集合中的项目可以通过字符串索引符来访问.该字符串索引符是人的姓名，与Person.Name属性相同：
public class Person : ICloneable
{
private string name;
private int age;
public string Name
{
get
{
return name;
}
set
{
name = value;
}
}
public int Age
{
get
{
return age;
}
set
{
age = value;
}
}

请高手帮忙啊

你继承是集合的接口吗?如果想通过Name来访问,可以在另外一个类定义person[]作为成员

public Person this[string nameIndex]
{
get
{
foreach(Person p in Persons)
{
if (p.Name=nameIndex)
{
return p;
}
}
}
}

class Persons : DictionaryBase
{
public void Add(string myKey, Person myPerson)
{
Dictionary.Add(myKey, myPerson);
}

public void Remove(string myKey)
{
Dictionary.Remove(myKey);
}

public Persons()
{

}

public Person this[string myKey]
{
get
{
return (Person)Dictionary[myKey];
}
set
{
Dictionary[myKey] = (Person)value;
}

}

}

static void Main(string[] args)
{
Persons persons = new Persons();
Person []arrayPerson = new Person[30];
for (int i = 0; i < 30; i++)
{
arrayPerson[i] = new Person();
arrayPerson[i].Name = i.ToString() + i.ToString();
arrayPerson[i].Age = i;
persons.Add(arrayPerson[i].Name, arrayPerson[i]);
}
foreach (DictionaryEntry eny in persons)
{
Console.WriteLine(eny.Value);
}
}

谢谢各位
