vb Replace 实现

今天改一个VB程序时发现程序自带的replace 函数不知什么原因竟然不好用了 所以就自己写了一个玩玩

记录一下

‘XGZ
‘替换字符
Private Function Replace1(ByVal resorce As String, ByVal Tag As String, ByVal value As String) As String
   Dim ret As String
   Dim i As Integer
   Dim j As Integer
   Dim t As Integer
   Dim offSet As Integer
   Dim pos As Integer
   Dim isTag As Boolean
   offSet = Len(Tag)  ‘跳跃
   Replace1 = ""

   For i = 1 To Len(resorce)
     isTag = False
     If Mid(resorce, i, 1) = Mid(Tag, 1, 1) Then
        t = i
        For j = 1 To offSet
          If Mid(resorce, t, 1) = Mid(Tag, j, 1) Then
            t = t + 1
          End If

        Next j
         If t - i = offSet Then ‘完全匹配
          isTag = True
          i = i + offSet - 1  ‘ i会自动加一所以在该处减一
         End If

         If Not isTag Then
           ret = ret & Mid(resorce, i, 1)
         End If

         If isTag Then
            ret = ret & value
         End If

     Else
       ret = ret & Mid(resorce, i, 1)
     End If

   Next i

  Replace1 = ret
End Function
