.NET API > Automatic merging of layers

I'm writing a web service that I'm hoping to use in conjunction with Workflow Designer. 

The desired outcome is to input a doc id in the workflow, along with other necessary parameters, and have the document automatically merge the layers. 

However, I can't figure out how to actually get the merge to happen. I believe that I need section numbers for the document, but I'm not sure where to go from here. Here's my code so far:

2.      public string mergeLayers(string uri, string userName, string passWord, string DWDocID, string fileCabinetName)
3.         {
4.             var message = "";
6.             try
7.             {
8.                 ServiceConnection sc = ConnectToDocuWare(uri, userName, passWord);
10.                 message = "Connected";
11.                 var org = sc.Organizations[0];
12.                 var fileCabinets = org.GetFileCabinetsFromFilecabinetsRelation().FileCabinet;
15.                 var fileCabinet = fileCabinets.Where(f => f.Name == fileCabinetName).FirstOrDefault();
17.                 var dialogInfoItems = fileCabinet.GetDialogInfosFromSearchesRelation();
18.                 var dialog = dialogInfoItems.Dialog[0].GetDialogFromSelfRelation();
20.                 var result = RunQuery(dialog, DWDocID);
21.                 var doc = getDoc(result, dialog, DWDocID);
23.                 var sections = doc.Sections;
25.                 try
26.                 {
27.                     message = "trying merge";
29.                     foreach (var s in sections)
30.                     {
32.                         new MergeAnnotationsParameters()
33.                         {
34.                             SectionNumber = int.Parse(s.Id)
35.                         };
37.                         message = "success";
38.                                 
39.                     }
40.                 }
41.                 catch (Exception ex)
42.                 {
43.                     message = ex.ToString();
44.                 }
45.             }
46.             catch (Exception ex)
47.             {
48.                 message = ex.ToString();
49.             }
51.             return message;
54.         }

Tom,
Here's a modification of something we had which borrows code from the examples, knowledgebase, and some of Joe Kaufman's code he posted a bunch of years ago. The example code will merge the layers in all of the sections (if it has multiple sections) of a document with a particular name ("blankPage1"), which is presumed to be in the query results.

awesome, thanks!
