Using TFS API, how can I find the comments which were made on a Code Review?

Question

I'm trying to figure out a way to find details about a Code Review Request / Response item in TFS2012.

I can query for all Code Review Request/Response items in the following way:

const string TfsUri = "http://mytfsserver:8080/tfs/Default ProjectCollection";

var tfs = new TfsTeamProjectCollection(new Uri(TfsUri));
var store = tfs.GetService<WorkItemStore>();

var versionStore = tfs.GetService<Microsoft.TeamFoundation.VersionControl.Client.VersionControlServer>();

var queryText = "SELECT [System.Id], 
                 FROM WorkItems 
                 WHERE [System.WorkItemType] = 'Code Review Request' 
                 or [System.WorkItemType] = 'Code Review Response'";
var query = new Query(store, queryText);

var result = query.RunQuery().OfType<WorkItem>();

This gives me a list of WorkItem types. When I loop over the result.FirstOrDefault().Fields property, it does give me some usefull information about the ShelveSet which is related to the Code Review, the "Associated Context". Using this information, I can query for the ShelveSet:

var versionStore = tfs.GetService<VersionControlServer>();
var shelveset = versionStore.QueryShelvesets("someCodeReviewId_xxxx","someUserName");

this gives me a ShelveSet item, but that's where I get stuck.

I've looked into the Microsoft.TeamFoundation.CodeReview namespace provided by both Microsoft.TeamFoundation.CodeReview.Components and Microsoft.TeamFoundation.CodeReview.Controls libraries, but this doesn't help me further either.

My question is: How can I find the actual comments made on a ShelveSet during a Code Review (both General comments and File comments) through the TFS API?

We have a new requirement to pull code review comments from TFS and here is a short example of what we implemented. The workItemId has to be queried through another method. You can even look it up in Visual Studio or through a TFS query in the UI. This is a small subset of what is available and what we are using. I found this link to be helpful after digging through MSDN.

 public List<CodeReviewComment> GetCodeReviewComments(int workItemId)
 {
        List<CodeReviewComment> comments = new List<CodeReviewComment>();

        Uri uri = new Uri(URL_TO_TFS_COLLECTION);
        TeamFoundationDiscussionService service = new TeamFoundationDiscussionService();
        service.Initialize(new Microsoft.TeamFoundation.Client.TfsTeamProjectCollection(uri));
        IDiscussionManager discussionManager = service.CreateDiscussionManager();

        IAsyncResult result = discussionManager.BeginQueryByCodeReviewRequest(workItemId, QueryStoreOptions.ServerAndLocal, new AsyncCallback(CallCompletedCallback), null);
        var output = discussionManager.EndQueryByCodeReviewRequest(result);

        foreach (DiscussionThread thread in output)
        {
            if (thread.RootComment != null)
            {
                CodeReviewComment comment = new CodeReviewComment();
                comment.Author = thread.RootComment.Author.DisplayName;
                comment.Comment = thread.RootComment.Content;
                comment.PublishDate = thread.RootComment.PublishedDate.ToShortDateString();
                comment.ItemName = thread.ItemPath;
                comments.Add(comment);
            }
        }

        return comments;
    }

    static void CallCompletedCallback(IAsyncResult result)
    {
        // Handle error conditions here
    }

    public class CodeReviewComment
    {
        public string Author { get; set; }
        public string Comment { get; set; }
        public string PublishDate { get; set; }
        public string ItemName { get; set; }
    }
