C# 4.0 银行应用程序的交易模块-已应答

我需要事务类中的帮助：

具有的事务类包含以下数据：

跟踪交易数量的计数器。每次存款或存款的增量 撤回。一个客户最多可以在一次登录中进行5次交易。 o 5项可能交易的历史记录。这将是一个美元金额数组，其中 负数表示取款，正数表示存款。清除历史 每次客户登录时

事务对象将执行以下操作： o更新历史记录以反映用户登录时进行的任何交易。跟上…的进展 如上所述在“交易数据”部分中生成的每个交易值。之后 每个事务，递增事务计数器。 o清除所有存储金额的历史记录并重置交易计数

您已经指定了从属性到函数的所有内容，只需编写代码即可

现在这将是一匙羹，但同样，您的更改是错误的

帐户类别：

public double getBalance()
{
return customerBalance;
 }
public bool Customerdeposit()
 {
double deposit = Convert.ToDouble(Console.ReadLine());
if (deposit <= 0)
 {
return false;
}
customerBalance = customerBalance + deposit;
return true;
}

public bool customerWithdraw()
{
double withdraw = Convert.ToDouble(Console.ReadLine());
{
if (withdraw <= 0 || customerBalance < withdraw )
{
return false;
}
customerBalance = customerBalance - withdraw;
return true;
}
}
 }

将为每笔交易拨打电话：

Transaction trans= new Transaction();
trans.credit(myCustAcc[user],500);

你的问题是？如何在一个银行应用程序中跟踪5笔交易我可以通过电子邮件给你我的代码bcz很难在这里粘贴代码你可以发布逻辑吗。（区块码）好的，我将发布logicI更新了存款和取款方法的一些代码，在调用它们的情况下进行切换，但我在那里遇到了一些问题，例如，如果客户有0美元余额，它应该不允许他们取款，但我的允许取款我们在编程中没有使用try-and-catch。我知道我们可以写if-else语句而不是try-and-catch。但我不确定是否用if-else语句编写代码。你能帮我吗？我用if-else代码更新了代码，用了事务类的代码。你的代码写错了（错误地使用了返回语句），试着理解代码，然后在纸上进行试运行。

public double getBalance()
{
return customerBalance;
 }
public bool Customerdeposit()
 {
double deposit = Convert.ToDouble(Console.ReadLine());
if (deposit <= 0)
 {
return false;
}
customerBalance = customerBalance + deposit;
return true;
}

public bool customerWithdraw()
{
double withdraw = Convert.ToDouble(Console.ReadLine());
{
if (withdraw <= 0 || customerBalance < withdraw )
{
return false;
}
customerBalance = customerBalance - withdraw;
return true;
}
}
 }
