using System; public class BankAccount {     static int nNextAccountNumber = 1000;     int nAccountNumber;     double dBalance;     public BankAccount() : this(0, 0) { }     public BankAccount(double dInitialBalance) :         this(0, dInitialBalance) { }     public BankAccount(int nInitialAccountNumber,                        double dInitialBalance) {         if (nInitialAccountNumber <= 0) {             nInitialAccountNumber = ++nNextAccountNumber;         }         nAccountNumber = nInitialAccountNumber;         if (dInitialBalance < 0) {             dInitialBalance = 0;         }         dBalance = dInitialBalance;     }     public string GetString() {         return String.Format("#{0} = {1:N}",                               nAccountNumber, dBalance);     } }
