大家帮我解释一个动态数组错误的问题
大家帮我看看我的这个程序动态数组怎么没用
这是个停车场的的添加
bool IfHuoche(ref HuoChe hc)
{
bool ifrigth = false;
bool ifContinue = true;
while (ifContinue)
{
Console.WriteLine("请输入车的排量,输入n退出本次添加！");
string input=Console.ReadLine();
if (input.ToLower()=="n")
{
ifContinue = false;
}
else if (int.Parse(input) >= 10 && int.Parse(input) <= 100)
{
hc.Pailiang = Int32.Parse(input);
Console.WriteLine("请输入您的车牌号！");
string carname = Console.ReadLine();
bool name = Worke.Juge10(carname);
if (name)
{
hc.Carnumber = carname;
Console.WriteLine("请输入您的姓名！");
hc.Ownername = Console.ReadLine();
if (carinfor == null)
{
carinfor = new ArrayList();
}
Car c = (Car)hc;
carinfor.Add(c);
ifrigth = true;
continue;
}
else
{
Console.WriteLine("您的必须是位的号码！");
}
}
else
{
Console.WriteLine("您的排量超标，不能进！");
}
}
return ifrigth;
}
我在线等 大家帮我看看 我都迷茫半天了
其中动态数组是 ArrayList carinfor

ArrayList carinfor = new ArrayList();
这么定义吧?
s114747867 发布留言 2008-7-22 13:52
这个没问题的 我先定义没实例化
itwalker 发布留言 2008-7-22 13:54
if (carinfor == null)
{
carinfor = new ArrayList();
}
以上代码不应该这样写.变量在类的构造中初始化.
s114747867 发布留言 2008-7-22 13:54
Car 是我做的一个类 用来存放车辆信息的 比如 pailiang ..... hc是Car的实例化对象

你要求达到什么效果?
yangyaming6208 发布留言 2008-7-22 15:16
好了,问题解决了
需要的话就回复我!
yangyaming6208 发布留言 2008-7-22 15:22
代码有点乱,看半天,原来是你的主函数出了问题,问你话,你半天不回(结果我在那猜你什么意图,郁闷!)
别的地方好像没问题(可能有的地方修改了),但主要问题在主函数上面.
下面是我修改过的主函数,不知道你是否满意?
static void Main()
{
Worke wor = new Worke();
bool isgoon = true;
while (isgoon)
{
Console.WriteLine("请输入要选择的种类：1进车;2出车;'N'表示退出");
string input = Console.ReadLine();
input = input.ToLower();
switch (input)
{
case "1":
wor.AddCar();
break;
case "2":
wor.DellCar();
break;
case "n":
isgoon = false;
break;
default:
break;
}
}
}
