vb.net关于arraylist奇怪的问题？

Dim amax_x As String，Dim amin_x As String，Dim upx As ArrayList = Nothing。。。调用如下1》amax_x = Arraylist_max(upx)2》amin_x = Arraylist_min(upx)注释1》和不注释1》2》中amin_x的值不同，注释了值是对的

你的算法有错误吧！
Dim Temp As String = Nothing
For i As Integer = 0 To arrlist.Count - 2
If Cint(arrlist(i)) < Cint(arrlist(i+1)) Then
Temp = arrlist(i+1)
Else
Temp = arrlist(i)
arrlist(i+1) = Temp
End If
Next i
Return Temp

用下面代码代替你上面的试试：
Dim Temp As String = arrlist(0)
For i As Integer = 1 To arrlist.Count - 1
If Cint(Temp) < Cint(arrlist(i)) Then
Temp = arrlist(i)
End If
Next i
Return Temp

求最小值的道理也相似啊！

追问

单独算最大最小值没问题，两个一起求就有问题了，从c语言上实现是没问题的，能指出来错在哪吗？谢谢
