也许你可以使用这样的东西：

Dim i As Integer



For i = 0 to temp.Count - 2

if（temp（i）= temp（i + 1））然后

我希望这对你有用。

Dim temp() As Integer = {1, 2, 2, 3, 4}
Dim i As Integer

For count = 0 To temp.Count - 1
If (temp(i).ToString = temp(i + 1).ToString) Then
ListBox2.Items.Add(i)
End If
Next

It shows me error like index was out of boundary. Please help me out

解决方案

Hi Surajit,
maybe you can use something like this:

Dim temp() As Integer = {1, 2, 2, 3, 4}
Dim i As Integer

For i = 0 To temp.Count - 2
If (temp(i) = temp(i + 1)) Then
ListBox2.Items.Add(temp(i))
End If
Next i

I Hope this is useful for you.
