Filepath lookup from id

[Andreas Zita]

Hi

The code below takes an id and return the corresponding image-stream. My
Album-class scans the provided dir for images and tags them with id and
filePath on server. In my current approach the m_album is re-generated each
time a request is made. However I would like it to be generated only once
when first run and then always be available on the server ... any ideas on
how a could speed this thing up?

private void Page_Load(object sender, System.EventArgs e)
{
m_album = new Album(Server.MapPath("Data"));
int id = Int32.Parse(Request.QueryString["id"]);
Item item = m_album.FindItemById(id);
if (item == null)
{
System.Drawing.Image image = System.Drawing.Image.FromFile(item.Path);
Response.ContentType = "image/jpeg";

thumbNail.Save(Response.OutputStream,System.Drawing.Imaging.ImageFormat.Jpeg
);
image.Dispose();
}
}

Sorry ... it should be "if (item != null)" of course ...

What is the problem? Is m_album.FindItemById slow? All you need to keep is
the item id and the path. You can make a little table in database if you
have one or a lookup file otherwise.
