留一个C#版。操作MONgoDB对数组进行增删改查

        [HttpPost]
        [ValidateInput(false)]
        public ActionResult Add(Title model)
        {
            List Item = new List();
            //生成俩选项并且添加
            Item item = new Item();
            item.cItemID = new ObjectId(Guid.NewGuid().ToString().Replace("-", "").Trim().Substring(0, 23));
            item.cItemName = Request["option1"] == null ? "1" : Request["option1"].ToString();

            Item item1 = new Item();
            item1.cItemID = new ObjectId(Guid.NewGuid().ToString().Replace("-", "").Trim().Substring(0, 23));
            item1.cItemName = Request["option2"] == null ? "2" : Request["option2"].ToString();
            Item.Add(item1);
            Item.Add(item);
            //将获取的List添加到实体的List中
            model.list = Item;
            string errorMsg;
            //插入
             bool result = _dbHelper.Insert
