C＃ - 代码重构以扩展功能
来计算一个区域的税率。
public class TaxCaculator
{
public Dictionary<RegionATaxRate, decimal> CalculateTax(List<SalesDocket> sales)
{
var result = new Dictionary<TaxRate, decimal>();
// pseudo-code logic to calculate Region A tax rate
return result;
}
}
我有一些代码 代码>和 regionAtaxrate，并返回包含针对单个regionAtaxrate s的总数。
在某些情况下，税收计算器类将使用如下：
var calculator = new TaxCalculator();
var result = calculator.CalculateTax(sales);
return result;
我要扩展此代码，以便将其用于多个区域-B区域B，区域C，区域D等地区的税率将不同。如何修改代码以允许？
I have some code which calculates the tax rates for one region, Region A.
public class TaxCaculator
{
public Dictionary<RegionATaxRate, decimal> CalculateTax(List<SalesDocket> sales)
{
var result = new Dictionary<TaxRate, decimal>();
// pseudo-code logic to calculate Region A tax rate
return result;
}
}
The CalculateTax() method processes a list of SalesDockets which contain an Amount and
a RegionATaxRate, and returns a dictionary containing the totals against the individual RegionATaxRates.
For some context, the TaxCalculator class will be used as follows:
var calculator = new TaxCalculator();
var result = calculator.CalculateTax(sales);
return result;
I want to extend this code so that it can be used for multiple regions - Region B, Region C, Region D, etc. However, each region will have a different tax rate. How can I modify my code to allow for this?

您可以将
regionAtaxrate更改为regiontaxrate，并在指示相关区域的region> reamialtaxrate中包含一个属性。例如：
You could change your
RegionATaxRatetoRegionTaxRateand include a property in theRegionTaxRatethat indicates the pertinent region.For example:
