folder upload

  string folder = "SasiReddy";
                var fileName = Path.GetFileName(file.FileName);
                string path1 = Server.MapPath("~/Users/" + folder);
                var path = Path.Combine(path1, fileName);
                System.IO.Directory.CreateDirectory(path1);


                string path2 = "~/Users/" + folder + "/" + fileName;


                file.SaveAs(path);
             
                midocument.Name = fileName;
                midocument.Path = path2; 
             
                db.MIDocuments.Add(midocument);
                db.SaveChanges();

It will create a folder in a project
