NHibernate - HQL - 添加和更改

添加：

         /// <summary>
         /// 等待乙方做出回应 A
         /// </summary>
         private void button2_Click_1(object sender, EventArgs e)
         {
             //使用NHibernate，进行存储
             Chinfo c = new Chinfo();

             c.CtinfoId = ID;
             c.Goodsinfo = "白玉手镯";
             c.Buyersinfo = "甲方";
             c.Sellerinfo = "乙方";
             c.Infocreatetime = DateTime.Now;//字段Infocreatetime是DateTime类型，所以此处不能ToString.
             c.Currentgoodsstate = "A";
             c.Goodsflow = "";
             c.Goodsflownowtime = DateTime.Now.ToString();
             c.CourierId = "";

             try
             {
                 NHelper.Session().Save(c);
                 NHelper.Trans().Commit();
                 MessageBox.Show("保存成功！", "提示");
             }
             catch (Exception ex)
             {
                 MessageBox.Show(ex.Message, "提示");
             }

             this.btn_A.Enabled = false;//禁用A
             this.btn_B.Enabled = true;//开启B
             this.btn_C.Enabled = true;//开启C
         }

修改：

         /// <summary>
         /// 乙方已同意请求 等待公司做出回应 B 1100000
         /// </summary>
         /// <param name="sender"></param>
         /// <param name="e"></param>
         private void button3_Click(object sender, EventArgs e)
         {
             try
             {
                 IQuery query = NHelper.Session().CreateQuery("from Chinfo c where c.CtinfoId = ?");

                 query.SetParameter(, ID);

                 IList<Chinfo> list = query.List<Chinfo>();

                 list[].Currentgoodsstate = "B";
                 list[].Goodsflow = "";
                 list[].Goodsflownowtime = list[].Goodsflownowtime + "-" +  DateTime.Now.ToString();

                 NHelper.Session().Update(list[]);

                 NHelper.Trans().Commit();

                 MessageBox.Show("修改成功！", "提示");
             }
             catch (Exception ex)
             {
                 MessageBox.Show(ex.Message, "提示");
             }

             this.btn_B.Enabled = false;//禁用B
             this.btn_C.Enabled = false;//禁用C
             this.btn_D.Enabled = true;//开启D
             this.btn_E.Enabled = true;//开启E
         }
