从数据库显示多个图像到asp.net页面

Question

i am creating a page that will display multiple images from the database... i can do it if i will only display one image, by using a page to be rendered as image.. something like this...

using (SqlDataReader reader = comm.ExecuteReader())
{
    Byte[] images = new Byte[]();
    while (reader.Read())
    {
         Response.BinaryWrite(images);
    }
}

and in the aspx file i have:

<asp:Image ID="imgPhoto" runat="server" ImageUrl="~/ShowImages/LoadImages.aspx" Height="100px" Width="100px" BorderWidth="1px" />

what i want to achieve is to display multiple images from the database without making a page to be rendered as image...

is there any way to work around with this... ?

thanks guys

Answer 1

I think the best way would be not using a database and storing the images on the disk - by storing images in binary form in a db column in this way you are limiting yourself.

If you are really set on storing images in this way then I could only suggest loading all the images you want from the db, and writing them to a temporary folder on the disk, then displaying a list of <img /> tags that reference their temporary location on the server.

All you do then is every time the images are requested you delete the ones from the previous request.

您需要制作一个按ID提供单个图像的页面，然后添加多个<img>标记，这些标记在查询字符串中引用具有不同ID的页面。
