Iterating through a SharePoint discussion list

One of those things that you think should be pretty straightforward…

Credit to Dave Ginn for finding the solution.

List itemList = new List();

foreach (SPListItem discussion in discList.Folders)
{
   //discussion.Title is discussion title
   SPQuery query = new SPQuery();
   query.Folder = discussion.Folder;
   SPListItemCollection messages = discList.GetItems(query);
   itemList.Add(new Discussion(discussion.Title, messages.Count));
}

//sort by most comments
itemList.Sort(delegate(Discussion p1, Discussion p2)
{ return p2.Comments.CompareTo(p1.Comments); });
