Sharepoint 2013 creating a new discussion on discussions list

Hi guys have you all ever tried creating a new discussion on discussions list programmatically?? I tried recently and got an issue. Like we all normally create and add an item  to a list I tried adding a discussion item on discussions list. Well it got created as the way I want but when I tried to reply to that discussion a message box popped and gave this following error message.

"Value does not fall within the expected range"

This is the C# code I used to create and add a new disussion on discussions list.


using (SPSite site = new SPSite("http://site-url"))
{
          using (SPWeb web = site.OpenWeb())
          {
                    SPList list = web.Lists["Discussions List"];
                    SPListItemCollection listItemCln = list.GetItems(list.Views["Management"]);

                    SPListItem item = list.Items.Add();
                    item["Title"] = "New Post";
                    item["Body"] = "Body of the post";
                    item.Update();
          }
}

This is the disussion got created

This is the error message box popped out when I tried to reply that discussion

So when I checked the log file it gave me this error message.

Failed to cache field with id "{1805e563-22cf-44ed-96f5-58ebb8a6cb80}", overwrite=0

Answer

I did some research and got some online help from others and found the solution. Discussions list is a type of list but we can't add items to it like we add on other lists. So there is a different way of adding the discussions on discussions list. This is working code:

using (SPSite site = new SPSite("http://site-url"))

{

          using (SPWeb web = site.OpenWeb())

          {

                    SPList list = web.Lists["Discussions List"];

                    SPListItem listItem = SPUtility.CreateNewDiscussion(list, "New Post");

                    listItem["Body"] = "Body of the post";

                    listItem.Update();   

          }

} 

Cheers :D
