c# - 如何在周末暂停工作，特别是在周五下午 5 点到周一早上 7 点之间

Question

我正试图在周末暂停工作。具体来说，周五下午 5 点停止工作，周一早上 6 点恢复工作。

这是我到目前为止所拥有的，但它没有按预期工作：

        var date = DateTime.Now;
        var testDay = date.AddHours(54);
        if ((testDay.DayOfWeek != DayOfWeek.Saturday && testDay.DayOfWeek != DayOfWeek.Sunday) || (testDay.DayOfWeek == DayOfWeek.Friday && testDay.Hour < 17) || (testDay.DayOfWeek == DayOfWeek.Monday && testDay.Hour > 6))
        {
            Console.WriteLine("Do work");
        }
        else
        {
            Console.WriteLine("Pause work");
        }

**今天是星期三，所以我将 testDay 创建为 54 小时后，这会将日期时间设置为我的条件，这将暂停工作。

我个人觉得扭转这一局面更容易，因为这样的条件比一周中每隔一天测试一次要少*：

“如果在星期五或星期六或星期日或星期一之前 5 之后”，则“暂停”，否则“做”

还结合了 Peter 的建议，因为它是减少长行并使代码更加自我记录的好方法

public static void Main()
{
    var date = DateTime.Now;
    while(date < DateTime.Now.AddDays(8)){
        Print(date);
        date = date.AddHours(3);
    }
}

static void Print(DateTime testDay){
    var dow = testDay.DayOfWeek;
    var isSat = dow == DayOfWeek.Saturday;
    var isSun = dow == DayOfWeek.Sunday;
    var isFriLate = dow == DayOfWeek.Friday && testDay.Hour >= 17;
    var isMonEarly = dow == DayOfWeek.Monday && testDay.Hour < 6;
    
    if (isFriLate || isSat || isSun || isMonEarly)
    {
        Console.WriteLine(testDay + " - Pause work");
    }
    else
    {
        Console.WriteLine(testDay + " - Do work");
    }
}
