DataGrid/DataList绑定图片和URL

网页中：
<ItemTemplate>
    <a href='' target="_blank" runat="server" id="vLnkImage">
        <asp:Image id="vImage" runat="server"></asp:Image>
    </a>
</ItemTemplate>

代码中：
if(e.Item.ItemIndex > -1)
{
    DataRowView drv = (DataRowView)e.Item.DataItem;
    System.Web.UI.WebControls.Image Img = (System.Web.UI.WebControls.Image)e.Item.FindControl("vImage");

    Img.ImageUrl = "/Images/+drv["c_FileName"].ToString();
   
    HtmlAnchor Link1 = (HtmlAnchor)e.Item.FindControl("vLnkImage");    
    Link1.HRef = "http://"+drv["c_URL"].ToString();
}
