如何在SSRS报告2014中显示所有工作日？

Public Function GetWorkingDays(ByVal startDate As DateTime, ByVal endDate As DateTime) As Integer
    Dim count As Integer = 0
    Dim currentDate As DateTime = startDate

    While currentDate <= endDate
        If currentDate.DayOfWeek <> DayOfWeek.Saturday AndAlso currentDate.DayOfWeek <> DayOfWeek.Sunday Then
            count += 1
        End If
        currentDate = currentDate.AddDays(1)
    End While

    Return count
End Function

=Code.GetWorkingDays(Parameters!StartDate.Value, Parameters!EndDate.Value)
