In this you will see how to get only the discussion topics using SharePoint object model.

I have a Discussion list named "Team Discussion" in which i have created two topics and each topic has few replies.

I want to retrieve only the two topics using SharePoint object model.

Code Snippet:

 
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.SharePoint;
using System.Xml;
 
namespace GetDiscussionTopics
{
    class Program
    {  
        public static void Main(string[] args)
        {
            using (SPSite site = new SPSite("http://serverName/sites/VJTesting/"))
            {
                using (SPWeb web = site.OpenWeb())
                {
                    SPList list = web.Lists.TryGetList("Team Discussion");
                    if (list != null)
                    {
                        // Empty Query is passed to get only the discussion topics
                        SPListItemCollection itemColl = list.GetItems(new SPQuery());
                        foreach (SPListItem item in itemColl)
                        {
                            System.Console.WriteLine(item["Title"].ToString());
                            System.Console.WriteLine(item["Replies"].ToString());
                        }
                        System.Console.ReadLine();
                    }
                    else
                    {
                        System.Console.WriteLine("List does not exists in the site");
                        System.Console.ReadLine();
                    }
                }
            }           
        }
    }
}


Using the above code snippet you will be able to get only the discussion topics.
