If you want to know to create document set Refer this link

We have to refer the two dlls

using Microsoft.Office.DocumentManagement.DocumentSets;

In Feature1.EventReceiver.cs I am writhing this code.

public class Feature1EventReceiver : SPFeatureReceiver

{

public override void FeatureActivated(SPFeatureReceiverProperties properties)

{

SPWeb web = properties.Feature.Parent as SPWeb;

SPContentType docSetCT = web.ContentTypes["Document Set"];

SPDocumentLibrary Doclib = web.Lists.TryGetList("DocumentLibraryName") as SPDocumentLibrary;

if (docSetCT != null)

{

try

{

Hashtable props = new Hashtable();

props.Add("DocumentSetDescription", "Sharepoint Related Documents");

SPFolder parentFolder = Doclib.RootFolder;

DocumentSet docSet = DocumentSet.Create(parentFolder, "SharePoint Documents", Doclib.ContentTypes.BestMatch(docSetCT.Id), props, true);

docSet.Item.ProgId = "SharePoint.DocumentSet";

//enabling the content type

Doclib.ContentTypesEnabled = true;

//enabling the versioning

Doclib.EnableVersioning = true;

Doclib.EnableMinorVersions = true;

Doclib.EnableModeration = true;

Doclib.Update();

docSet.Item.Update();

}

catch (Exception e)

throw e;
