今天编东西的时候遇到点问题，请各位不吝赐教........
class Customer
{
private string name;
private int roomnum;
private int day;
public Customer()
{
name = ""; roomnum = 0; day = 0;
}
public Customer(string name, int roomnum, int day)
{
this.name = name; this.roomnum = roomnum; this.day = day;
}
public void show()
{
Console.WriteLine("{0:F2},{1:F2},{2}", name, roomnum, day);
}
public string Name
{
set { return name; }
get { name = value; }
}
public int Roomnum
{
set { return roomnum; }
get { roomnum = value; }
}
public int Day
{
set { return day; }
get { day = value; }
}

static void Main(string[] args)
{
Customer c = new Customer();
ArrayList clist = new ArrayList();
string a;
Console.Write("是否输入住户资料（y/n）：");
a = Console.ReadLine();
char x;
x = char.Parse(a);
while (x == 'y')
{
Console.Write("请输入姓名：");
c.Name = Console.ReadLine();
string j, k;
Console.Write("请输入入住房间号：");
j = Console.ReadLine();
c.Roomnum = int.Parse(j);
Console.Write("请输入姓名：");
k = Console.ReadLine();
c.Day = int.Parse(k);
clist.Add(c);
Console.Write("是否输入住户资料（y/n）：");
a = Console.ReadLine();
x = char.Parse(a);
}
for (int n = 0; n < clist.Count; n++)
c.show();
}
}
看一下，貌似有问题的说，还有一点觉得写得不对的就是，把信息读入到数组里的时候总有问题....读不进，最后提一点这是个旅馆住店人员进行登记控制台应用程序程序

private int day;

{

}
public Customer(string name, int roomnum, int day)
{
this.name = name; this.roomnum = roomnum; this.day = day;
}

{
Console.WriteLine("{0:F2},{1:F2},{2}", name, roomnum, day);
}
public string Name
{
get { return name; }
set { name = value; }
}
public int Roomnum
{
get { return roomnum; }
set { roomnum = value; }
}
public int Day
{
get { return day; }
set { day = value; }
}

static void Main(string[] args)
{

Customer c = new Customer();
ArrayList clist = new ArrayList();
string a;
Console.Write("是否输入住户资料（y/n）：");
a = Console.ReadLine();
char x;
x = char.Parse(a);
while (x == 'y')
{
Console.Write("请输入姓名：");
c.Name = Console.ReadLine();
string j, k;
Console.Write("请输入入住房间号：");
j = Console.ReadLine();
c.Roomnum = int.Parse(j);
Console.Write("请输入天数：");
k = Console.ReadLine();
c.Day = int.Parse(k);
clist.Add(c);
Console.Write("是否输入住户资料（y/n）：");
a = Console.ReadLine();
x = char.Parse(a);
}


for (int n = 0; n < clist.Count; n++)
{

c.show();
}
//Console.Read();
}
}

}
还有一点小问题，如果输入一个是可以，但是输入两个就出现错误，要用到结构数组吧，但是我一直弄不出来
