c#度量转换类
本文关键字：转换 度量 | 更新日期: 2023-09-27 18:15:22
我一直在写一个用于厨房测量的类，现在它只有体积或液体测量，我这样称呼它:
ktchnmsrmnts.VolumeMeasurements(number), current_measurement, to_measurement);
，从那里，大多数人都很容易找出里面的代码，只是一些简单的数学。现在我的问题是，我需要添加一个选项，说'嘿，他有17.50杯，让它是1加仑，和1 1/2杯。
我正在考虑为'to_measurement'添加一个新案例它会检查这个数字是否大于最高测量值，比如19杯大于加仑，然后它把它变成1加仑，然后把剩余的量发送到直线上，但我从不在厨房里使用品脱，所以也许可以添加另一个选项来转换它。我不知道我被困住了，是的，我知道代码是基本的，但符合我的需求，无论如何，一半…
如果你需要我的完整代码，给你:

很难确切地说出你在要求什么，但我确实看到了这个:
现在我的问题是我需要添加一个选项，说'嘿，他有17.50杯，让它成为1加仑，和1 1/2杯。
您需要获取一组测量值，并通过它们循环重新计算余数。我强烈建议您将方法代码提取到类变量和辅助方法中。
下面是一些示例代码，应该可以帮助您。你需要填空。
public string ConvertToDescription(double amount, string originalMeasurement, params string[] toMeasurements)
{
StringBuilder sb = new StringBuilder();
double valueToConvert = amount;
string priorMeasurement = originalMeasurement;
double displayAmount;
for (int i = 0; i < toMeasurements.Count; i++)
{
if (i > 0)
sb.Append(" ");
double convertedAmount = VolumeMeasurements(valueToConvert, priorMeasurement, toMeasurement[i]);
// Check if last item so we don't trim wanted decimals.
if (i < toMeasurements.Count - 1)
displayAmount = Math.Floor(convertedAmount)
else
displayAmount = convertedAmount;
valueToConvert = convertedAmount - displayAmount;
priorMeasurement = toMeasurements[i];
// You will need to add logic here to display fractions if needed.
sb.AppendFormat("{0} {1}", displayAmount, toMeasurements[i]);
if (fixedAmount == 0)
break;
}
return sb.ToString();
}
请记住，这些都没有经过测试，我真的希望这是你想要的。这应该能让你走上正轨。您需要找到一种方法将最后一次转换中的小数转换为分数并实现它。这至少会让你得到"1加仑1.5杯"
