Get Discussion List Items from SharePoint Discussion Forum

If you are trying to retrieve all the root items of the Discussion List this way , it's not going to work :
SPSite site = new SPSite("Site URL");
SPWeb web = site.OpenWeb();
SPList list1 = web.Lists["DiscussionListName"];
SPListItemCollection coll = list1.Items ;



Well Here is the right way of doing it :-)
SPSite site = new SPSite("Site URL");
SPWeb web = site.OpenWeb();
SPList list1 = web.Lists["DiscussionListName"];
SPListItemCollection coll =list1.Folders ;
