1、银行存取款案例(C#编程)classSavingsAccount{//类字段用于存储帐号、余额和已获利息privateint_accountNumber;privatedouble_balance;privatedouble_interestEarned;//利率是静态的，因为所有帐户获得的利息相同privatestaticdouble_interestRate;//构造函数初始化类成员publicSavingsAccount(intaccountNumber,doublebalance){this._accountNumber=accountN

2、umber;this._balance=balance;}//只读AccountNumber属性publicintAccountNumber{get{return_accountNumber;}}publicdoubleInterestEarned{get{return_interestEarned;}set{//验证数据if(value<0.0){Console.WriteLine("利息不能为负数");return;}_interestEarned=value;}}publicstaticdoubleInterestRate{get{retu

3、rn_interestRate;}set{//验证数据if(value<0.0){Console.WriteLine("利率不能为负数");return;}else{_interestRate=value/100;}}}publicdoubleBalance{get{if(_balance<0)Console.WriteLine("没有可用余额");return_balance;}set{_balance=value;}}voidputmoney(doublemoney){Console.WriteLine("您原来的存款余额为：{0}",_ba
