Question

我有以下代码：

Public Shared Function DPLoadData() As String
    Dim s As StringBuilder = New StringBuilder("<head><meta http-equiv=""content-type"" content=""text/html;charset=utf-8"" /><META HTTP-EQUIV=""REFRESH"" CONTENT=""900"">")
    s.Append("<style type=""text/css"" media=""all""> body{font-family: Arial;}h4{font-size: 10pt;font-weight: bold;white-space: nowrap;margin-top: 0; margin-bottom: 10px;}")
    s.Append("th{font-size: 9pt;font-weight: normal;text-align: center;white-space: nowrap;}td{font-size: 9pt;}.content td{border: solid 1px #dadada;}")
    s.Append(".content th {border: solid 1px #dadada;background-image: url(""tbl_header_row_bg.gif""); background-repeat: repeat-x; white-space: nowrap;}</style></head>")
    s.Append("<h3>" & "Daily Plan" & "</h3>")
    Dim strCurrDay As String = ""
    s.Append("<h5>" & strCurrDay & "</h5>")

    Dim CurrDateFirstDay As Date = DateAdd(DateInterval.Day, 1, Now)
    strCurrDay = FormatDateTime(CurrDateFirstDay, DateFormat.LongDate)

    s.Append("<h5>" & strCurrDay & "</h5>")
    s.Append(LoadDataGroupByDate(CurrDateFirstDay))
    Return s.ToString()
End Function

该函数生成一个带有表格的HTML文件，并用预订填充它。目前，HTML文件显示明天的预订（例如，如果今天是星期一，则显示星期二的预订）。到现在为止还挺好。我想要的是，如果今天是星期五，HTML文件应该显示星期一而不是星期六的预订。这可能吗？

我的解决方案：

        If value.DayOfWeek = DayOfWeek.Friday Then

            Dim CurrDateFirstDay As Date = DateAdd(DateInterval.Day, 3, Now)

            strCurrDay = FormatDateTime(CurrDateFirstDay, DateFormat.LongDate)
            s.Append("<h5>" & strCurrDay & "</h5>")
            s.Append(LoadDataGroupByDate(CurrDateFirstDay))
        Else
            Dim CurrDateFirstDay As Date = DateAdd(DateInterval.Day, 1, Now)

            strCurrDay = FormatDateTime(CurrDateFirstDay, DateFormat.LongDate)
            s.Append("<h5>" & strCurrDay & "</h5>")
            s.Append(LoadDataGroupByDate(CurrDateFirstDay))

        End If

如果您创建这样的方法：

Public Function GetNextWeekDay() As Date
    Dim value As Date = Date.Now
    Do
        value = value.AddDays(1)
    Loop While (value.DayOfWeek = DayOfWeek.Saturday) Or (value.DayOfWeek = DayOfWeek.Sunday)
    Return value
End Function

然后你可以像这样设置你的变量：

Dim CurrDateFirstDay As Date = GetNextWeekDay()

获取下一周工作日（跳过周末）以显示HTML格式的数据
