skier类中想要添加如年龄、性别 该怎么实现？
using System;using System.Collections;
using System.Text;
//using Queue;
//using Icollection;
namespace SKier
{
struct Skier
{
public Skier(string name)
{
myname = name;
// yearsold = 0;
}
public string myname;
public int yearsold;
}
class Program
{
static void Main(string[] args)
{
SkiLift lift = new SkiLift();
lift.Run();
}
}
public class SkiLift
{
public SkiLift()
{
_theLift = new Queue();
}
protected void DisplayStatus()
{
Console.WriteLine("there are current {0} skier on the lift,", _theLift.Count);
if (_theLift.Count > 0)
{
Skier firstSkier = (Skier)_theLift.Peek();
Console.WriteLine("the first skier will be {0}.", firstSkier.myname);
Console.WriteLine("Skier on the lift:");
Array skiers = _theLift.ToArray();//?
foreach (Skier askier in skiers)
{
Console.WriteLine("\t" + askier.myname+askier.yearsold);
}
}
}
protected SkiAction GetNextAction()
{
SkiAction result= SkiAction.Quit;
bool done = false;
while (done==false)
{
Console.WriteLine("A) Add a skier to the lift:");
Console.WriteLine("R) del a skier to the lift");
Console.WriteLine("Q) Quit");
switch (Console.ReadLine().ToUpper())
{
case "A":
result = SkiAction.AddSkier;
done = true;
break;
case "R":
result = SkiAction.RemoveSkier;
done = true;
break;
case "Q":
result = SkiAction.Quit;
done = true;
break;
// default: break;
}
}
return result;
}
public void Run()
{
bool done = false;
while (!done)
{
DisplayStatus();
SkiAction choice = GetNextAction();
switch (choice)
{
case SkiAction.AddSkier:
string name;
int old;
do
{
Console.WriteLine("Skier is name:");
name = Console.ReadLine();
Console.WriteLine("how old are you:");
// old = Console.ReadLine();//怎么输入整形被读出到控制台？
}
while (name.Length == 0);
Skier newSkier = new Skier(name);
_theLift.Enqueue(newSkier);
break;
case SkiAction.RemoveSkier:
if (_theLift.Count == 0)
{
Console.WriteLine("the lift is empty:");
}
else
{
Skier next = (Skier)_theLift.Dequeue();
Console.WriteLine("{0} has left the lift", next.myname);
}
break;
case SkiAction.Quit:
Console.WriteLine("Gookbye");
done = true;
break;
default:
break;
}
}
}
protected enum SkiAction { AddSkier, RemoveSkier, Quit };
protected Queue _theLift;
}
}
在这里的Queue类是不是要更换别的类HashTable？
有什么更好的解决办法吗？
--------------------编程问答-------------------- 没人吗
自己顶下了 --------------------编程问答-------------------- 没有看懂 到底要干嘛啊 --------------------编程问答-------------------- 就是要在struct Skier
{
public Skier(string name)
{
myname = name;
// yearsold = 0;
}
public string myname;
//public int yearsold;
}
这个类中多几个变量，要在输入时候有提示输入，和输出
我现在输入的只有myname 我还想输入年龄，性别等
该怎么该？
另外一个问题： switch (choice)
{
case SkiAction.AddSkier:
string name;
int old;
do
{
Console.WriteLine("Skier is name:");
name = Console.ReadLine();
Console.WriteLine("how old are you:");
// old = Console.ReadLine();//怎么输入整形被读出到控制台？
}
这里我想读取整型变量 该怎么修改？
--------------------编程问答--------------------
struct Skier //结构体～
{
public Skier(string name, int age, bool gender)
{
_myname = name;
_age = age;
_gender = gender;
}
private string _myname;
private int _age;
private bool _gender;
}
// old = Console.ReadLine();//怎么输入整形被读出到控制台？
int age;
bool isValid = true;
do
{
if(isValid )
Console.WriteLine("how old are you:");
else
Console.WriteLine("Your input is invalid, how old are you:");
isValid = false;
}while(!int.Tryparse(Console.ReadLine(), out age))
--------------------编程问答-------------------- --------------------编程问答-------------------- 结构体里也可以写set,get方法～ --------------------编程问答--------------------
--------------------编程问答-------------------- 这里保存选手的时候还有个问题，提示：
struct student
{
public student(string inputName, int inputAge, bool inputGender)
{
_name = inputName;
_age = inputAge;
_gender = inputGender;
}
private string _name;
public string name
{
set
{ _name = value; }
get
{ return _name; }
}
private int _age;
public int age
{
set
{
if (value <= 0 || value > 120)
{
throw new Exception("the age you input is not valid");
}
else
_age = value;
}
get
{
return _age;
}
}
private bool _gender;
public bool gender
{
set
{ _gender = value; }
get
{ return _gender; }
}
}
A) Add a skier to the lift:
R) del a skier to the lift
Q) Quit
a
Skier is name:
ddsfs
how old are you:
13
there are current 2 skier on the lift,
the first skier will be sss.
Skier on the lift:
sss0
ddsfs0
应该是sss 12
ddsfs 13
才对！
是不是Queue不能保存这样的2维 要该成ashTable行不行？
补充：.NET技术 , C#
