I am getting images in Image control. However I want to display name of each image but not able to get image name in label.

Please help.

Code Behind

string[] filesindirectory = Directory.GetFiles(Server.MapPath( filePath))
List<String> images = new List<string>(filesindirectory.Count());
foreach (string item in filesindirectory)
{
    if (IsImageFile(item))
    {

        images.Add(String.Format("~/../singimages/{0}", System.IO.Path.GetFileName(item)));
    }
DataList1.DataSource = images;
DataList1.DataBind();

<asp:DataList ID="DataList1" runat="server" RepeatDirection="Horizontal" >
    <ItemTemplate>
        <asp:Image ID="Image2" runat="server" ImageUrl='<%# Container.DataItem %>' Width="350px" Height="250px" />
        <%-- <asp:Label ID="label1" runat="server" Text='<%#Container.DataItem.ToString() %>' />--%>
