Add document set to library SharePoint Online

Question

Hello,

 

I'm trying to create a document set in a document library SharePoint online.

 

I have a special document set for this : Events

 

 

 

 I need to create this event in à webservice Azure, and i try with this code :

 

ClientContext clientContext = GetonlineContext();
            Web spWeb = clientContext.Web;
            var formLib = spWeb.Lists.GetByTitle("Event");
            ContentTypeCollection listContentTypes = formLib.ContentTypes;
            ContentTypeId dsCtId = new ContentTypeId();
            clientContext.Load(listContentTypes, types => types.Include(type => type.Id, type => type.Name, type => type.Parent));
            var result = clientContext.LoadQuery(listContentTypes.Where(c => c.Name == "Events"));
            clientContext.ExecuteQuery();
            ContentType docsetCT = result.First();
            ContentTypeId ctid = docsetCT.Id;
            DocumentSet.Create(clientContext, formLib.RootFolder, value.name, ctid);
            clientContext.ExecuteQuery();

 

private class Configuration
        {
            public static string ServiceSiteUrl = "https://****.sharepoint.com";
            public static string ServiceUserName = "*****";
            public static string ServicePassword = "******";
        }
        static ClientContext GetonlineContext()
        {
            var securePassword = new SecureString();
            foreach (char c in Configuration.ServicePassword)
            {
                securePassword.AppendChar(c);
            }
            var onlineCredentials = new SharePointOnlineCredentials(Configuration.ServiceUserName, securePassword);
            var context = new ClientContext(Configuration.ServiceSiteUrl);
            context.Credentials = onlineCredentials;
            return context;
        }

 

But when i execute, there is no document add to the library.

 

Can you please help me ? I'm lost ...
