求一asp字符串转换算法。

[gmlxf]

去除重复值

原字符串：str="1,1,2,2,2,3,3,4,5,6,6,7,12,12,23,34,34,.........."
目标字符串：str="1,2,3,4,5,6,7,12,23,34,.........."

说明：原字符串str最后数字结尾。

建议先将字符串转成数组，在数组中去掉重复很简单嘛

我象下面一下解决。

strArray=split(str,",")
str=","
for i=0 to ubound(str)
if InStr(str,","&strArray(i)&",")=0 then
str=str& strArray(i) & ","
end if
next
str=mid(str,2,len(str)-1)

[gmlxf]

error
以下纠正
str=mid(str,2,len(str)-2)
