Dim ids As String
Dim n As Integer = 6 '未来天数,含今天,所以实际是未来7天
For Each dr As DataRow In DataTables("员工").DataRows
    Dim dt As Date = dr("出生日期")
    Dim dt1 As New Date(Date.Today.Year,dt.Month,dt.Day)
    Dim dt2 As  New Date(Date.Today.AddDays(n).Year,dt.Month,dt.Day)
    If (dt1 >= Date.Today AndAlso dt1 < Date.Today.AddDays(n)) OrElse (dt2 >= Date.Today AndAlso dt2 < Date.Today.AddDays(n)) Then
        ids = ids & "," & dr("_Identify")
    End If
Next
If ids > "" Then
    ids = ids.Trim(",")
    Tables("员工").filter = "[_Identify] In (" & ids &")"
End If

我认为红色的代码没必要加 ,只用绿色的不就行吗?
