vb.net – 检查当天是否在给定工作日的两个范围内

2019年8月4日 236次阅读

用户可以在表单中选择开始日和结束日. (比如星期一到星期一.)

如何检查当前工作日是否在这两个工作日之间？

Dim WEstart As DayOfWeek = 5 'Friday
Dim WEend As DayOfWeek = 1 'Monday

If Date.Now.DayOfWeek >= WEstart And Date.Now.DayOfWeek <= WEend Then
   Return True
Else
   Return False
End If

不行.

最佳答案 试试看.这将检查星期五和星期一之间的天数.也就是说,它在周五,周六,周日和周一返回“真”.

如果星期几是星期二,星期三或星期四,则返回false.

Dim startday As DayOfWeek = DayOfWeek.Friday
    Dim endday As DayOfWeek = DayOfWeek.Sunday
    Dim today As DayOfWeek = DateTime.Now.DayOfWeek

    If endday >= startday Then
        Return (today >= startday AndAlso today <= endday)
    Else
        Return (today >= startday OrElse today <= endday)
    End If
