asp删除数组中的重复值

asp使用数组时我们经常会碰到数组中出现重复的值，为了去掉这些重复的值可以用如下函数:

<%
Function MoveR(Rstr)
 Dim i,SpStr
 SpStr = Split(Rstr,",")
 For i = 0 To Ubound(Spstr)
  If I = 0 then
   MoveR = MoveR & SpStr(i) & ","
  Else
   If instr(MoveR,SpStr(i))=0 and i=Ubound(Spstr) Then
    MoveR = MoveR & SpStr(i)
   Elseif instr(MoveR,SpStr(i))=0 Then
    MoveR = MoveR & SpStr(i) & ","
   End If
  End If
 Next
End Function
str1 = "a,b,c,d,e,c,d,a,f,g,g,h,e"
response.write MoveR(str1)
%>
