asked on how to check an arralist with individual Alphanumeric entries.
I want to search an arraylist of entries and if an entry is is there do not duplicate the entry and jsut move on. If the entry is new I want to add it to the arraylist.
If _ExcelGageID.startswith("L") then
_ExcelArraylist.add(wirelessArray(1)
end if
Visual Basic.NET

Hi cmdolcet;
If using a basic data type such as integer then doing the following should do what you need.

Dim al As New ArrayList
'' ...
Dim itemToInset As Integer = 4
If Not al.Contains(itemToInset) Then
al.Add(itemToInset)
End If

Sorry just saw that. I am looking to add an alphanumeric number like "L12345" to the arraylist.

If not basic types such as integers, double, ... what is the object structure and what fields will determine equality?
