Default populating a drop down with a file list

my db stores the location of the image, not the image. Of course, the image has been previously loaded, I want to store the full URL of the image into the database. For this I use a drop down list so the user can select it.

So far I've been using this:



    '---------------------Image Listing from directory peopertypics in images



    Dim strDir As String



    strDir = Server.MapPath("~/images/propertypics")



    Dim dirInfo as New System.IO.DirectoryInfo(strDir)

    Dim arrFiles as System.IO.FileInfo() = dirInfo.GetFiles()



    dtgDirInfo.DataSource = arrFiles

    dtgDirInfo.DataBind()



    '---------------------end image listing




and in the drop down all I get for now is the actual physical path something like c:\xxx\xxx\xxx.jpg

My list box command is the following:



<asp:listbox id="dtgDirInfo" runat="server" Rows="1" DataTextField="fullname" DataValueField="fullname" />



Any ideas of how I can get the URL instead of the physical path?



Thank you so much.

I did this and it seems to work pretty well...

Dim aryFiles() As String = System.IO.Directory.GetFiles(Server.MapPath("~/images"))
Dim sRootPath As String = Server.MapPath("~")
Dim i As Integer

For i = 0 To aryFiles.Length - 1
    aryFiles(i) = aryFiles(i).Replace(sRootPath, "~")
Next

'proceed with binding to control

What are the value names for this code? I mean to do the binding. I have to assign a value to the listbox datafieldvalue.

Thank you.
