Show files from 2 different folders in a single Gridview

问题

Is it possible to show files from 2 different folders (c:\test1 and c:\test2) in the same gridview?

I work in VB.net (VS 2010)

Thanks!

Yes. Get list of all the files using Directory.GetFiles() into a single IEnumerable<string> and bind it to a GridView.

This is how you'll do it in c#.

            List<string> allFiles = new List<string>();
            allFiles.AddRange(Directory.GetFiles(@"C:\test1\*"));
            allFiles.AddRange(Directory.GetFiles(@"C:\test2\*"));

            yourGV.DataSource = allFiles;
            yourGV.DataBind();

Try something like this:

Dim files As New List(Of String)()
files.AddRange(GetAllFilesFromDir("C:\foo")) 
files.AddRange(GetAllFilesFromDir("C:\bar"))
'GetAllFilesFromDir() must return IEnumerable string
gv.DataSource = files
gv.DataBind()

<asp:gridview ID="gv" runat="server">
    <Columns>
        <asp:TemplateField>
            <ItemTemplate>
                <asp:Label ID="file" runat="server" Text='<%# Container.DataItem %>'></asp:Label>
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:gridview>

You hadn't shown your code in your question, so the above example demonstrates how this might be done generally.

yes. Add them both as collections to List() or any other collection type. Then bind that set to the gridview.
