Hi i want to run a user as administrator to create terms.

 SPSite site = SPContext.Current.Site;
        SPSecurity.RunWithElevatedPrivileges(() =>
            using (SPSite secureSite = new SPSite(site.ID))
                TaxonomySession ts = new TaxonomySession(secureSite);
                TermStore termStore = ts.TermStores["Managed Metadata Service"];
                Group group = termStore.Groups["MyGroup"];

                TermSet termSet = group.CreateTermSet("Termset");

                termSet.CreateTerm("Term", 1033);



I can only create terms if the current user are a Contributor in the termstore, but i want to run this user as administrator without adding the user to the contributor in the term store?


The reason your code is not working is that TaxonomySession uses the user from the HttpContext. I found this link which is in German but the suggested code looks like this:

var siteId = SPContext.Current.Site.ID;
HttpContext oldContext = null;
   //Save actual context and null
   oldContext = HttpContext.Current;
   HttpContext.Current = null;
      using (var elevatedSite = new SPSite(siteID))
         var taxonomySession = new TaxonomySession(elevatedSite);
         var termStore = taxonomySession.DefaultKeywordsTermStore;

         //put your logic here

   HttpContext.Current = oldContext;

  • Have you tried to debug the code? I pasted it into my VM first and it worked, although I didn't add anything to the TermStore. – Andreas Jun 9 '15 at 7:44
  • SPSite site = SPContext.Current.Site; get object reference not set? – Batistuta Jun 9 '15 at 8:04
  • If SPContext.Current is null this is not related to this issue. Are you working in the context of a webpart? – Andreas Jun 9 '15 at 8:11
