Excel vba排除号码

数据源为0-9的随机数字字符串。需要从这个字符串中找出0-9没出现的数字，如123，即结果为0456789

这里我们用了三种方法去查询出结果，用对比反选，正则表达式和 字典。

        Function wb(rg As Range)

        Dim i As Byte

        s = "0123456789"

        For i = 1 To Len(rg)

            s = Replace(s, Mid(rg, i, 1), "")

        Next i

        wb = s

        End Function

正则表达式排除数字：

        Function zb(rg As Range)

        Dim re

        Set re = CreateObject("vbscript.regexp")

            s = "0123456789"

            re.Global = True

            re.Pattern = Replace("[n]", "n", rg.Value)

            zb = re.Replace(s, "")

        End Function

使用字典排除数字：    

        Sub jlj()

            On Error Resume Next

            Dim h

            Application.ScreenUpdating = False

            g = Cells(Rows.Count, 1).End(xlUp).Row

            arr = Range("a1:a" & g)

            For o = 1 To UBound(arr)

                Set zz = CreateObject("VBScript.RegExp")

                Set zd1 = CreateObject("scripting.dictionary")

                Set zd = CreateObject("scripting.dictionary")

                zz.Global = True

                zz.Pattern = "\d"

                Set m = zz.Execute(arr(o, 1))

                For Each n In m

                    zd(n * 1) = ""

                Next

                For t = 0 To 9

                    zd1(t) = ""

                Next

                v = zd1.keys

                For Each b In zd.keys

                    For c = 0 To 9

                        If b * 1 = v(c) Then

                            zd1.Remove (v(c))

                            GoTo 100

                        End If

                    Next

        100:

                Next

                For Each r In zd1.keys

                    h = h & r

                Next

                i = i + 1

                Cells(i, 5) = h

                Set zd = Nothing: Set zd1 = Nothing: h = Nothing: v = Nothing: m = Nothing

            Next

        End Sub
