這就是定義一個類，還有什么難的……uj5u.com熱心網友回復：
class Account{
public string [] AccountNumber { get; set; }
public string Name { get; set; }
public string ID { get; set; }
public double Balance { get; set; }
public void Deposit()
{
}
public void Draw()
{
}
public void Transfer()
{
}
}
————————————————————————————————————
static void Main(string[] args)
{
Account a = new Account();
string[] s_arry ={ "Account112233001" ,"Account112233002", "Account112233003" };
a.AccountNumber = s_arry;
foreach (string str in a.AccountNumber)

Console.WriteLine(str);
}
int result = a.AccountNumber.Length;
Console.WriteLine("共有"+result+"個賬戶");

非常感謝，謝謝謝謝謝謝

提幾個小問題，第一 ID應該時 uint比較好， Balance 用decimal，精度較好第二，AccountNumber 應該時 static 的，用戶應該時銀行的屬性，而不是實體的，在Account的 new 方法里做增加
