I want to images from those three folder into datalist how can i do that.At present i am showing images present only in image folder using this code:<asp:DataList ID="dlImages" runat="server" RepeatColumns="3" CellPadding="3" style="margin-left: 0px"><ItemTemplate><a id="imageLink" href='<%# Eval("ImageName","~/Images/{0}") %>' title='<%#Eval("Description") %>' rel="lightbox[Brussels]" runat="server" ><asp:Image ID="Image1" ImageUrl='<%# Bind("ImageName", "~/Images/{0}") %>' runat="server" Width="100" Height="100" /></a></ItemTemplate><ItemStyle BorderColor="Brown" BorderStyle="dotted" BorderWidth="3px" HorizontalAlign="Center" VerticalAlign="Bottom" /></asp:DataList>Now i want to show images in that datalist from three different folder how can i do thatThanks in advance 解决方案<asp:datalist id="dlImages" runat="server" repeatcolumns="3" cellpadding="3" xmlns:asp="#unknown"> Style="margin-left: 0px" onitemdatabound="dlImages_ItemDataBound"> <itemtemplate> <a id="imageLink"> rel="lightbox[Brussels]" runat="server"> <img id="Image1" runat="server" /> </a> </itemtemplate> <itemstyle bordercolor="Brown" borderstyle="dotted" borderwidth="3px" horizontalalign="Center"> VerticalAlign="Bottom" /> </itemstyle></asp:datalist>public partial class _Default : System.Web.UI.Page { DataTable resultTable; protected void Page_Load(object sender, EventArgs e) { // Dummy data resultTable = new DataTable(); resultTable.Columns.Add("ImageName"); resultTable.Columns.Add("Description"); resultTable.Columns.Add("ID"); DataRow dr = resultTable.NewRow(); dr["ID"] = 1; dr["Description"] = "Description 1"; dr["ImageName"] = "Sharepoint-2010-powered-by-itgroove.jpg"; resultTable.Rows.Add(dr); dr = resultTable.NewRow(); dr["ID"] = 2; dr["Description"] = "Description 2"; dr["ImageName"] = "nature_6.jpg"; resultTable.Rows.Add(dr); dr = resultTable.NewRow(); dr["ID"] = 3; dr["Description"] = "Description 3"; dr["ImageName"] = "werkzoekende.png"; resultTable.Rows.Add(dr); dlImages.DataSource = resultTable; dlImages.DataBind(); } protected void dlImages_ItemDataBound(object sender, DataListItemEventArgs e) { string filepath = GetImagePath(Convert.ToString(resultTable.Rows[e.Item.ItemIndex]["ImageName"])); // set anchor tag Object objImageLink = e.Item.FindControl("imageLink"); if (objImageLink != null) { HtmlAnchor anchor = objImageLink as HtmlAnchor; anchor.HRef = filepath; anchor.DataBind(); } // set image control Object objImage = e.Item.FindControl("Image1"); if (objImage != null) { HtmlImage img = objImage as HtmlImage; img.Src = filepath; img.Width = 100; img.Height = 100; img.DataBind(); } } // To get image path public string GetImagePath(string imgName) { string imgFolderPath = Server.MapPath("~/Images"); string[] seprator = {"Images"}; string filepath = string.Empty; var file = Directory.GetFiles(imgFolderPath, imgName, SearchOption.AllDirectories).FirstOrDefault(); if (file == null) { // Handle the file not being found } else { filepath = "~/Images" + file.Split(seprator, StringSplitOptions.None)[1]; filepath = filepath.Replace("\\", "/"); } return filepath; } } 这篇关于如何将不同文件夹中的图像显示为datalist的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
