无法检查数组中是否存在值

Question

尝试检查数组中是否存在值的时候， If Not IsError(Application.Match(arrString, RegM, 0)) Then...但是由于某种原因，它不起作用。 我也尝试了以下方法，但没有成功Application.WorksheetFunction.CountIf(DirArray2, RegM)

当我检查msgbox中的值时，似乎一切正常，但仍然无法正常工作（在msgbox下面显示了例如“ DMM | DMM | TEST”

MsgBox RegM & " | " & Application.WorksheetFunction.CountIf(DirArray2, RegM)

我引用了整个函数，因为也许您在代码中发现了导致问题的内容

Sub mk_RegExp()
    If Sheets("MISC").Range("C62") = True Then
        Dim objRegex As Object
        Dim RegMC As Object
        Dim RegM As Object
        Dim item As Variant
        Dim DirArray As Variant
        Dim DirArray2 As Variant
        Dim DirArr As Variant
        Dim test As Variant
        '------------------------------------------------------------------------------------------------
        Sheets("LI").Range("C12:DJ42").Font.Color = vbBlack
        '------------------------------------------------------------------------------------------------
        arr = Sheets("MISC").Range("R4:R145").Value
        LastRow = Sheets("MISC").Cells(Rows.Count, "L").End(xlUp).Row
        DirArray = Join(Application.Transpose(Sheets("MISC").Range("L4:L" & LastRow).Value), "|")
        LastRow2 = Sheets("MISC").Cells(Rows.Count, "M").End(xlUp).Row
        DirArray2 = Join(Application.Transpose(Sheets("MISC").Range("M4:M" & LastRow2).Value), "|")
        arrString = Join(Application.Transpose(Sheets("MISC").Range("M4:M" & LastRow2).Value), ",")
        DirArr = DirArray & "|" & DirArray2
        '------------------------------------------------------------------------------------------------
        Set objRegex = CreateObject("vbscript.regexp")
        With objRegex
            .Global = True
            .Pattern = DirArr

           For Each item In arr
                If .test(Range(item).Value) Then
                    Set RegMC = .Execute(Range(item).Value)
                    For Each RegM In RegMC
                        If Not IsError(Application.Match(arrString, RegM, 0)) Then
                            'MsgBox RegM & " | " & Application.WorksheetFunction.CountIf(DirArray2, RegM)
                            Range(item).Characters(RegM.FirstIndex + 1, RegM.Length).Font.Color = RGB(0, 176, 80)
                        ElseIf RegM = "COL" Or RegM = "CRT" Then
                            Range(item).Characters(RegM.FirstIndex + 1, RegM.Length).Font.Color = RGB(0, 176, 240)
                        Else
                            Range(item).Characters(RegM.FirstIndex + 1, RegM.Length).Font.Color = RGB(247, 150, 70)
                        End If
                    Next
                End If
            Next item
        End With
    Else
        Sheets("LI").Range("C12:DJ42").Font.Color = vbBlack
    End If
End Sub

除了我的评论

Sub test_array()

Dim a() As Variant

a = Application.Transpose(Range("a1:a5"))

Debug.Print Join(a, "|")

Debug.Print Application.WorksheetFunction.Match("Test 2", a, 0)
Debug.Print Application.WorksheetFunction.Match("Test 2", Join(a, "|"), 0)


End Sub

第二行错误，第一行还可以。
