好的,以下是一个简单的股票交易类的示例代码:
```csharp
public class StockTrading
{
private decimal _commissionRate;
private decimal _buyStampDutyRate;
private decimal _sellStampDutyRate;
public StockTrading(decimal commissionRate, decimal buyStampDutyRate, decimal sellStampDutyRate)
{
_commissionRate = commissionRate;
_buyStampDutyRate = buyStampDutyRate;
_sellStampDutyRate = sellStampDutyRate;
}
public bool BuyStock(string stockCode, int quantity, decimal price)
{
decimal totalCost = CalculateTotalCost(quantity, price, _buyStampDutyRate, _commissionRate);
// TODO: 实现购买股票的逻辑
return true; // 购买成功
}
public bool SellStock(string stockCode, int quantity, decimal price)
{
decimal totalRevenue = CalculateTotalRevenue(quantity, price, _sellStampDutyRate, _commissionRate);
// TODO: 实现卖出股票的逻辑
return true; // 卖出成功
}
private decimal CalculateTotalCost(int quantity, decimal price, decimal stampDutyRate, decimal commissionRate)
{
decimal totalCost = quantity * price * (1 + stampDutyRate) * (1 + commissionRate);
return totalCost;
}
private decimal CalculateTotalRevenue(int quantity, decimal price, decimal stampDutyRate, decimal commissionRate)
{
decimal totalRevenue = quantity * price * (1 - stampDutyRate) * (1 - commissionRate);
return totalRevenue;
}
}
```
在这个类中,我们定义了三个私有字段 `_commissionRate`、`_buyStampDutyRate` 和 `_sellStampDutyRate`,分别表示佣金、买入印花税和卖出印花税率。
在构造函数中,我们初始化这些字段的值。然后,我们定义了两个公共方法 `BuyStock` 和 `SellStock`,分别用来实现买入和卖出股票的逻辑。
在这两个方法中,我们调用了两个私有方法 `CalculateTotalCost` 和 `CalculateTotalRevenue`,分别用来计算买入和卖出股票的总成本和总收入。
最后,我们可以根据具体的业务需求,在 `BuyStock` 和 `SellStock` 方法中实现具体的股票交易逻辑。
