Have the following code which creates a table of all the images in a folder.
VB:
Sub Page_Load(sender as Object, e as EventArgs)
If Not Page.IsPostBack then
Dim dirInfo as New DirectoryInfo(Server.MapPath("/images"))
articleList.DataSource = dirInfo.GetFiles("*.jpg")
articleList.DataBind()
End If
End Sub
Body:
<asp:DataGrid runat="server" id="articleList" AutoGenerateColumns="False" ShowHeader="false">
<Columns>
<asp:BoundColumn DataField="Name" />
</Columns>
</asp:DataGrid>
The results look something like this:
aa_01.jpg
aa_02.jpg
aa_03.jpg
bb_01.jpg
bb_02.jpg
cc_01.jpg
cc_02.jpg
cc_03.jpg
cc_04.jpg
...
What I want to do now is group all these by the first two characters and get the total number for each and insert them into individual strings. So for the above example it would be something like:
Dim aa As String = 3
Dim bb As String = 2
Dim cc As String = 4
Any ideas how?
