How to get Whats New field value from TFS

Question

I cannot find Whats New field on TFS via c# . I can get WorkItem, but where Whats New field?

How to get WorkItem:

 public WorkItemCollection GetAllWorkItemsFromCollection(String collectionName, String date)
    {
        String collNameTemp = String.Empty;
        try
        {

            var collNodes = this.GetAllCollectionsRaw();
            foreach (var c in collNodes)
            {

                TmpCl cl = new TmpCl(c, _InstanceId, _configurationServer);

                var wis = cl.teamProjectCollection.GetService<WorkItemStore>();

                foreach (var p in cl.projCollectionInfo)
                {

                    if (p.Name == collectionName)
                    {

 string newnewquery= @"SELECT [System.Id], [Microsoft.VSTS.Common.ClosedDate],  [System.WorkItemType], [System.Title], [System.AssignedTo], [System.State] 

            FROM WorkItems 

            WHERE [System.TeamProject] = '" + p.Name + "' AND " +

       "   [System.WorkItemType] = 'Task' AND [System.ChangedDate] > '" + date + "' " +

        "    ORDER BY [System.Id]";


                        collNameTemp = p.Name;


                        Query qry1 = new Query(wis,newnewquery, null, false);
                        ICancelableAsyncResult car1 = qry1.BeginQuery();

                        WorkItemCollection items1 = qry1.EndQuery(car1);


                        return items1;

                    }
                    else { }
                }


            }

        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }

        return null;       

public TmpCl(CatalogNode c,String InstanceId,TfsConfigurationServer configurationServer)
  {
      try
      {
          Guid collectionId = new Guid(c.Resource.Properties[InstanceId]);
          teamProjectCollection = configurationServer.GetTeamProjectCollection(collectionId);

          Iis = (ICommonStructureService)teamProjectCollection.GetService(typeof(ICommonStructureService));
          projCollectionInfo = Iis.ListAllProjects();


      }
      catch (Exception ex)
      {
          Console.WriteLine( ex.Message);
      }
  }

So, i can get Completed Work, for example:

    public String GetCompletedWorkByTaskWI(String collectionName, WorkItem taskWI)
    {
        try
        {
            foreach (Field f in taskWI.Fields)
            {
                if (f.Value != null && f.Name.Equals("Completed Work"))
                {

                    return Convert.ToString(f.Value);

                }
                else if (f.Value == null && f.Name.Equals("Completed Work"))
                {
                    return "0";
                }
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }
        return "0";
    }

But how to get Whats New field? I cannot find it!

EDIT: Sorry, it was another SQL query. This query uses for get WorkItem objects.

PS - Fields :

EDIT: This is query for get tasks wich contains Whats New value (tfs query generator):

SELECT [System.Id], [System.WorkItemType], [System.Title], 
       [System.AssignedTo],  [System.State]
    FROM WorkItems WHERE [System.TeamProject] = @project  
                     AND  [System.WorkItemType] <> ''  
                     AND  [System.State] <> ''  
                     AND  [WW.WhatsNew] CONTAINS '/' 
    ORDER BY [System.Id]

Answer 1

I found this field.

The ansqwer is- Get Revisions from WorkItem,get Revision, and go:

if ((f.Name.Equals(Consts.WHATS_NEW) && f.Value != null))
                    this.WhatsNew = (String)f.Value;

Answer 2

I'd suggest to add the What's new field to the SELECT list:

SELECT [System.Id], [System.WorkItemType], [System.Title], 
       [System.AssignedTo], [System.State], [WW.WhatsNew] 
    FROM WorkItems WHERE [System.TeamProject] = @project  
                     AND  [System.WorkItemType] <> ''  
                     AND  [System.State] <> ''  
                     AND  [WW.WhatsNew] CONTAINS '/' 
    ORDER BY [System.Id]

Many of the other fields that are returned are TFS out-of-the-box fields, so I assume that some these are returned even if they are not explicitly contained in the SELECT list.
