Sample for creating a a Article page programatically

 public void createuserwiki(string title)
        {
            SPWeb spweb = SPContext.Current.Web;

            PublishingWeb publishingWeb = PublishingWeb.GetPublishingWeb(spweb);
            string pageName = title + ".aspx";

            PageLayout[] pageLayouts = publishingWeb.GetAvailablePageLayouts();
            PageLayout currPageLayout = pageLayouts[9];
            PublishingPageCollection pages = publishingWeb.GetPublishingPages();
          
           PublishingPage newPage = pages.Add(pageName, currPageLayout);

            newPage.ListItem[FieldId.PublishingPageContent] = "";
            newPage.ListItem[FieldId.RollupImage] = "";
            newPage.ListItem[FieldId.Title] = "";

            newPage.ListItem.Update();
            newPage.Update();
            newPage.CheckIn("This is just a comment");
            SPFile page = SPContext.Current.Web.GetFile("/Pages/" + title + ".aspx");
            using (SPLimitedWebPartManager wpmgr = page.GetLimitedWebPartManager(PersonalizationScope.Shared))
            {
                XmlElement p = new XmlDocument().CreateElement("p");
                p.InnerText = "Edit this webpart to add content on this Page";
                // page.DeleteProperty(pageLayouts[0]);

                ContentEditorWebPart cewp = new ContentEditorWebPart
                {
                    Content = p
                };
                wpmgr.AddWebPart(cewp, "Header", 0);
