Create a mysite(personal site) Using the Object Model

Below code is using object model creating the my sites dynamically.


            SPSite site = new SPSite("http://win-rgqt3bch3nk:22929/sites/Test");

            SPWeb web = site.OpenWeb();
            // SPWeb web = SPContext.Current.Web;


            web.AllowUnsafeUpdates = true;

         
            if (ApproveitemId > 0)
            {
                SPList thislist = web.Lists["Requests"];
                SPListItem item = thislist.Items.GetItemById(ApproveitemId);
                string AStatus = item["Approval_Status"].ToString();
                string strYes = "Yes";
                if (AStatus == strYes)
                {
                    string mysiteusername = item["Username"].ToString();
                     //SPUser mysiteuname = web.AllUsers[mysiteusername];
