我们做用户核对报告，因为我们需要找到分配给特定用户的电子邮件 ID。

例如

客户报告用户名可能如下所示 

Sathish K
Sathya A

但在我们的合并报告中，实际用户名将如下所示

Sathish Kothandam
Sathya Arjun

所以我创建了一个宏

Sub test
Dim t as string 
t= “Sathish K”
msgbox(getemailId(t))
End sub

    Dim rng As Range

Function getemailId(Byval findString As String)
    With ActiveWorkbook.Sheets("CONSOLIDATED").Range("B:B")
        Set rng = .find(What:=findString, LookIn:=xlValues)
        If Not rng Is Nothing Then
‘ B – Column contains username C – Email id of the user
            getemailId = rng.offset(0,1).value
        Else
            find1 = 0
        End If
    End With
End Function

我的宏在上述情况下完美运行，但有时我可能会收到如下用户名

Satish Kothandam
Sathiya Arjun

但这一次它返回 0 。有什么办法可以实现我的目标吗？希望我解释清楚？

请看下面的示例代码。

Sub test()

Dim str1 As String, str2 As String
Dim str1c As String, str2c As String

str1 = "Sathish"
str2 = "Satish"

str1c = SOUNDEX(str1)
str2c = SOUNDEX(str2)

MsgBox str1c = str2c

End Sub

您可以使用 levenshtein 算法。它计算两个字符串之间的距离。

来源维基媒体

Function levenshtein(a As String, b As String) As Integer

    Dim i As Integer
    Dim j As Integer
    Dim cost As Integer
    Dim d() As Integer
    Dim min1 As Integer
    Dim min2 As Integer
    Dim min3 As Integer

    If Len(a) = 0 Then
        levenshtein = Len(b)
        Exit Function
    End If

    If Len(b) = 0 Then
        levenshtein = Len(a)
        Exit Function
    End If

    ReDim d(Len(a), Len(b))

    For i = 0 To Len(a)
        d(i, 0) = i
    Next

    For j = 0 To Len(b)
        d(0, j) = j
    Next

    For i = 1 To Len(a)
        For j = 1 To Len(b)
            If Mid(a, i, 1) = Mid(b, j, 1) Then
                cost = 0
            Else
                cost = 1
            End If

            ' Since Min() function is not a part of VBA, we'll "emulate" it below
            min1 = (d(i - 1, j) + 1)
            min2 = (d(i, j - 1) + 1)
            min3 = (d(i - 1, j - 1) + cost)

'            If min1 <= min2 And min1 <= min3 Then
'                d(i, j) = min1
'            ElseIf min2 <= min1 And min2 <= min3 Then
'                d(i, j) = min2
'            Else
'                d(i, j) = min3
'            End If
'            In Excel we can use Min() function that is included
'            as a method of WorksheetFunction object
            d(i, j) = Application.WorksheetFunction.Min(min1, min2, min3)
        Next
    Next
    levenshtein = d(Len(a), Len(b))

End Function
