<script runat="server">

    void Page_Load()
    {
        DirectoryInfo di = new DirectoryInfo(Server.MapPath("~/Documents"));

        Array al = di.GetFiles("*.*");
    }

</script>

How do I get al into a IDataSource object so I can access it from <asp:treenode>??

I've tried everything, nothing works. Please help me get this array into <asp:treenode>

I'm sure its simple but C# is just different enough from PHP to thwart me- it looks similar but works completely differently...

Look I can give u the idea here, but can't code it for you, there can be two simple possible ways that I know:
1. Create an XML with distinction of Folders and files like

<RootDirectroy>
  <FolderName>
    <FileName></FileName>
  </FolderName>
  <FolderName>
    <FileName></FileName>
  </FolderName>
</RootDirectory>
Now bind this as datasource to the Treeview control.

2. For each directories and files, create treenodes for directories first, and the treenodes for files under it. finally add the parent directory to the main RootDirectory node.

Try any of the above, I hope you will be able to get through.

Don't expect too much, too soon.

Thanks for your help but I need something dynamic- I've got hundreds of files and folders to display on a company intranet.

This is frusturating. Why can't ASP.net just use arrays like every other programming system in the world? Why this irritatingly different way of doing things?

I have the data in a normal array, I just can't get to it! Please help!
