您好...
已用于从db.like
显示图像的数据列表 .aspx:

Hi...
Am used datalist for display images from db.like
.aspx:

<asp:DataList ID="DataList1" runat="server" Height="82px"

        ItemStyle-HorizontalAlign="Center" RepeatColumns="3" Width="180px" EnableViewState="true">
<ItemStyle HorizontalAlign="Center"></ItemStyle>
        <ItemTemplate>
        <asp:Image ID="img1" ImageUrl='<%# Bind("Name", "~/Images/{0}") %>' Width="250" Height="180" runat="server" />
        <asp:HyperLink ID="HyperLink1" Text='<%# Bind("Name") %>' NavigateUrl='<%# Bind("Name", "~/Images/{0}") %>' runat="server"/>
            </ItemTemplate>
    </asp:DataList

<asp:Button ID="btnpv" Text="previous" runat="server" style="font-weight: 700" Visible="true" Width="66px" onclick="btnpv_Click" />
            

    <asp:Button ID="btnx" Text="Next" runat="server" style="font-weight: 700" Visible="true" Width="52px" onclick="btnx_Click" />

aspx.cs:

DirectoryInfo dir = new DirectoryInfo(MapPath("Images"));
            FileInfo[] files = dir.GetFiles();
            ArrayList listitems = new ArrayList();
foreach (FileInfo info in files)
            {
                    listitems.Add(info);
            }
// bind images on conditional
            adsource = new PagedDataSource();
            adsource.DataSource = listitems;
            adsource.PageSize = 3;
            adsource.AllowPaging = true;
            adsource.CurrentPageIndex = pos;
            btnx.Visible = true;
            //btnx.Enabled = !adsource.IsFirstPage;
            btnpv.Visible = true;
            btnpv.Enabled = !adsource.IsFirstPage;
            DataList1.DataSource = adsource;
            DataList1.DataBind();

谢谢你.

Thank u.

您没有提及要在何处和何处显示图像，以及如何列出这样做的可能性.

1.显示图像基于使用HANDLER的用户选择 [ 2.存储在数据库中并在网格视图中检索. [ 3.CP文章，用于在ASP.NET中显示二进制图像 [ ^ ]

希望您找到出路，
问候

Hi,
You have not mentiones from where and to where you want to display the images, and how am listing the near possibilities of doing the same.

1.Displaying Image based on the User selection using HANDLER [^]

2.Storing in Database and retrieving in the Grid view.[^]

3.CP Article to Display Binary Images in ASP.NET[^]

Hope you find your way out,
Regards,
