NHibernate

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 = "1000000";
            c.Goodsflownowtime = DateTime.Now.ToString();
            c.CourierId = "234235245";

            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：

                IQuery query = NHelper.Session().CreateQuery("from Chinfo c where c.CtinfoId = ?");

                query.SetParameter(0, ID);

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

                list[0].Currentgoodsstate = "B";
                list[0].Goodsflow = "1100000";
                list[0].Goodsflownowtime = list[0].Goodsflownowtime + "-" +  DateTime.Now.ToString();

                NHelper.Session().Update(list[0]);

                NHelper.Trans().Commit();

                MessageBox.Show("修改成功！", "提示");
            }
