Dim bol2 As Boolean For i As Integer = t.Rows.Count -1 To 0 Step -1 bol2 = False Dim r As Row = t.Rows(i) If r.IsNull("核实情况_情况类别") = False Then For Each item As String In nms If nms.Contains(r("核实情况_情况类别")) = False Then \'nms为集合 bol2 = True Else r.Delete() End If Exit For Next If bol2 Then Continue For End If End If Next |
