帮解决个问题，看看下面代码哪有问题，为什么没有输出结果。谢谢
在博客园里找的代码但不输出结果，我不知道哪写错了，帮忙看一下。谢谢
EmployeeID类
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace ConsoleApplication1
{
public class EmployeeID
{
public EmployeeID()
{
}
private string ID { get; set; }
public EmployeeID(string id)
{
this.ID = id;
}
public override string ToString()
{
return base.ToString();
}
public override int GetHashCode()
{
return base.GetHashCode();
}
public override bool Equals(object obj)
{
EmployeeID emp = obj as EmployeeID;
if (emp == null) return false;
if (this.ID == emp.ID) return true;
return false;
}
}
}
EmployeeData类
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace ConsoleApplication1
{
public class EmployeeData
{
public EmployeeData()
{
//
}
public string Name
{
get;
set;
}
public int Age
{
get ;
set ;
}
public string Gender
{
get;
set;
}
public EmployeeData(string name, int age, string gender)
{
this.Name = name;
this.Age = age;
this.Gender = gender;
}
}
}
输出窗口：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Collections;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
Hashtable hst = new Hashtable();
hst.Add(new EmployeeID("0"),new EmployeeData("a",12,"female"));
hst.Add(new EmployeeID("1"),new EmployeeData("b",10,"male"));
hst.Add(new EmployeeID("2"), new EmployeeData("c", 10, "female"));
abc:
Console.WriteLine("Please input the employee ID:");
string userid= Console.ReadLine();
if (userid.Trim() != "exit")
{
EmployeeData emp = (EmployeeData)hst[new EmployeeID(userid.Trim())];
if (emp != null)
{
Console.WriteLine(emp.Name);
Console.WriteLine(emp.Age);
Console.WriteLine(emp.Gender);
}
goto abc;
}
}
}
}
帮看看哪有问题，不能输出HashTable 值。谢谢
