谁帮我看看这段代码哪地方出错了
using System;using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Collections;
namespace ConsoleApplication11
{
class student
{
public string name;
public char sex;
public student(string name1, char sex1)
{
name = name1;
sex = sex1;
}
public string answer()
{
return "mingzi:" + name + "xingbie:" + sex;
}
}
class Program
{
static void Main(string[] args)
{
Hashtable h = new Hashtable();
student p = new student("aa",'b');
h.Add("甲", p);
student p1 = new student("bb", 'c');
h.Add("乙", p1);
student p2 = new student("cc", 'd');
h.Add("丙", p2);
ICollection c = h.Values;
IEnumerator ie = h.GetEnumerator();
while (ie.MoveNext())
{
string s = ((student)ie.Current).answer();
Console.WriteLine(s);
}
Console.ReadKey();
}
}
}

正解
补充：.NET技术 , C#
