Hello,

I'm not sure I've understood your question but if you want to know the id of a content type,list content type, go to the list parameter, clicl on the content type et check the url, you should see the ctype parameter which is the content type

Hope this help!

Hey,

I am not actually why you are geting so troubled while finding the ID of content type

sing System;
using Microsoft.SharePoint;

namespace Test
{
   class ConsoleApp
   {
      static void Main(string[] args)
      {
         using (SPSite site = new SPSite("http://localhost"))
         {
            using (SPWeb web = site.OpenWeb())
            {
               // Search for a built-in content type on lists in the site.
               SPContentTypeId parentId = SPBuiltInContentTypeId.Document;
               foreach (SPList list in web.Lists)
               {
                  SPContentTypeId matchId = 
                     list.ContentTypes.BestMatch(parentId);
                  // Report a match only if the list is not hidden 
                  // (e.g. Master Page Gallery).
                  if (parentId.IsParentOf(matchId) && !list.Hidden)
                  {
                     Console.WriteLine("{0} has the {1} content type.",
                                        list.Title, 
                                        list.ContentTypes[matchId].Name);
                     Console.WriteLine("parent content type id: {0}",
                                        parentId.ToString());
                     Console.WriteLine("  list content type id: {0}", 
                                        matchId.ToString());
                  }
               }
            }
         }
         Console.Write("\nPress ENTER to continue...");
         Console.ReadLine();
