asp下去除數組中重復的項的方法

<%
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 
response.write MoveR("abc,abc,dge,gcg,dge,gcg,die,dir,die")

%>

結果是：abc,dge,gcg,die,dir

如果是兩個數組進行對比，去掉相同的數組元素：

<%
		Function mover(farray,sarray)
		a = Split(farray, ",")
			Set dic = CreateObject("Scripting.Dictionary")
			For k=0 To UBound(a)
			 If a(k)<> "" Then dic.Add "_" & a(k), a(k)
			Next
			a = Split(sarray, ",")
			For k=0 To UBound(a)
				If a(k)<> "" Then
					If dic.Exists("_" & a(k)) Then
					dic.Remove "_" & a(k)
					End If
				End If
			Next
			items = dic.Items()
			Set dic = Nothing
			moveR=Join(items, ",")
		End Function
n1 = "a,b,1,11,12,13,14,15,16,17,19,20,22"
n2 = "a,1,12,14,18,19,20"
response.write mover(n1,n2)

%>

 結果是：

3.數組A中有為空的元素(如a=array("ww","ss","","dd","","ee")), 
 想把這些空元素從數組A中去掉.並把去掉空元素有的數組賦給數組B.

str=""
for i = lbound(A) to ubound(A)
if A(i)<>"" then
if i<>lbound(A) then str = str + "," end if
str = str & A(i)
end if
next
b = split(str,",")
