Add a Document Set using Managed Client Object Model

I love Client Object Modeling. SharePoint 2010 has made easy how to talk to the SharePoint objects from Client machines.

Adding a docset pro grammatically using Object modeling should be easy. I was trying to add a new doc set using Managed Client Object Model. Remember docset is nothing but a item in a list. And document libraries are again nothing but just a list with different look and feel. Below function creates a new docset with the defined content type.



public int AddDocSet(string siteUrl, string listName, string docSetContentTypeName, string newDocSetName)
        {
            ClientContext clientContext = new ClientContext(siteUrl);
            clientContext.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials;
            Web web = clientContext.Web;
            List list = clientContext.Web.Lists.GetByTitle(listName);


            clientContext.Load(clientContext.Site);


            ContentTypeCollection listContentTypes = list.ContentTypes;
            clientContext.Load(listContentTypes, types => types.Include
                                              (type => type.Id, type => type.Name,
                                              type => type.Parent));


            var result = clientContext.LoadQuery(listContentTypes.Where(c => c.Name == docSetContentTypeName));


            clientContext.ExecuteQuery();


            ContentType targetDocumentSetContentType = result.FirstOrDefault();


            ListItemCreationInformation newItemInfo = new ListItemCreationInformation();
            newItemInfo.UnderlyingObjectType = FileSystemObjectType.Folder;
            newItemInfo.LeafName = newDocSetName;
            ListItem newListItem = list.AddItem(newItemInfo);


            newListItem["ContentTypeId"] = targetDocumentSetContentType.Id.ToString();
            newListItem["Title"] = newDocSetName;
            newListItem.Update();


            clientContext.Load(list);
            clientContext.ExecuteQuery();
            return newListItem.Id;


        }


Call this function by passing the appropriate site url, list name , docsetcontent type, and the doc set name.
