Question

我在代码中定义了这些变量，我想一步对其进行初始化，该怎么办？

class FemaleClub(name: String, country: String): Club(name = name, country = country)

例如：

int currentYearSavingDays, currentYearSavingXMins, currentYearSavingNXMins, currentYearUsedDays, currentYearUsedXMins, yearLimitRemainingDays, yearLimitRemainingXMins, totalYearlyDays, totalYearlyXMins, totalSavingDays, totalSavingMins, totalUsableDays, totalUsableMins, nextYearTotalUsableDays, nextYearTotalUsableMins, dayWorkMinutes, previousYearRemainingDays, previousYearRemainingMins;

Answer 1

我不愿一次全部声明它们。除了丑陋的阅读之外，没有必要。

相反，这似乎是class或struct的一组字段的理想选择。

在C＃中，value type个字段被分配，并由memory manager自动初始化为其默认值。因此，在这种特殊情况下，如果仅为这些值创建了新的类/结构，则无需显式初始化它们。

请注意，只要您小心不要违反single responsibility principle，就可以将它们也保留为当前类中的字段。

还要注意，如果答案为local variables，则此答案中描述的策略将不起作用。正如this answer所解释的，尽管初始化语义相同，但是未初始化的局部变量的使用通常是一个错误，在C＃中是不允许的。在这种情况下，我认为最好在自己的行上声明和初始化每个变量。

Answer 2

我所知道的就是这个。

int currentYearSavingDays, currentYearSavingXMins, currentYearSavingNXMins, currentYearUsedDays, currentYearUsedXMins, yearLimitRemainingDays, yearLimitRemainingXMins, totalYearlyDays, totalYearlyXMins, totalSavingDays, totalSavingMins, totalUsableDays, totalUsableMins, nextYearTotalUsableDays, nextYearTotalUsableMins, dayWorkMinutes, previousYearRemainingDays, previousYearRemainingMins;
currentYearSavingDays = currentYearSavingXMins = currentYearSavingNXMins = currentYearUsedDays = currentYearUsedXMins = yearLimitRemainingDays = yearLimitRemainingXMins = totalYearlyDays = totalYearlyXMins = totalSavingDays = totalSavingMins = totalUsableDays = totalUsableMins = nextYearTotalUsableDays = nextYearTotalUsableMins = dayWorkMinutes = previousYearRemainingDays = previousYearRemainingMins = 0;

Answer 3

您可以这样声明和初始化：

int iOne = 1, iTwo = 2, iThree = 3;

变量初始化是可选的

此行

   int iOne,iTwo,iThree;

将所有变量都设置为零。
