WSS Practice: Create and Reply to Discussions

Another thing I’d not done through the SharePoint Object Model was create or reply to a Discussion. This sounded a bit more complicated, but I found a helpful post of ‘Common Discussion Operations‘…

My Code was:
//** Create a Discussion thread
SPList disc = site.Lists["Discussion"];
SPListItem topic = SPUtility.CreateNewDiscussion(disc.Items, "Test Thread");
topic["Body"] = "Lorem Ipsum and so on";
topic.Update();
//** Create a reply
SPListItem reply = SPUtility.CreateNewDiscussionReply(topic);
reply["Body"] = "This is, like, a reply, dude!";
reply.Update();

This code will create a new thread, and create a single reply to it. Once you’ve got the SPUtility object, it’s all much simpler than I’d expected.

The SPUtility object is found in the Microsoft.SharePoint.Utilities namespace – all sorts of things tucked away in there.

    When I use your code to create a new reply I get the error below even though it still adds the reply
