C#实现执行数据库事务案例

static bool CreateUserOrder(UserOrder model, string Ids) { List<string> SQLStringList = new List<string>(); List<DbParameter[]> Parameters = new List<DbParameter[]>(); StringBuilder strSql = new StringBuilder(); //添加OrderInfor SqlParameter[] parameters1 = OrderInforDAL.BuildOrderInforAddParameter(model.UserId, model.OrderCode, Ids, ref strSql); SQLStringList.Add(strSql.ToString()); Parameters.Add(parameters1); //添加UserOrder SqlParameter[] parameters2 = BuildUserOrderAddParameter(model, ref strSql); SQLStringList.Add(strSql.ToString()); Parameters.Add(parameters2); //清空购物车 SqlParameter[] parameters3 = BasketDetailDAL.BuildUpdateParameter(true, Ids, ref strSql); SQLStringList.Add(strSql.ToString()); Parameters.Add(parameters3); //修改优惠劵状态 if (model.CouponId > 0) { SqlParameter[] parameters4 = CouponDAL.BuildUpdateParameter(model.CouponId, 1, model.OrderCode, ref strSql); SQLStringList.Add(strSql.ToString()); Parameters.Add(parameters4); } return access.ExecuteSqlTran(SQLStringList, Parameters, true); }

 

接下来贴出两个个详细的方法作参考：

internal static SqlParameter[] BuildOrderInforAddParameter(int UserId, string OrderCode, string Ids, ref StringBuilder strSql)
        {
            strSql = new StringBuilder();
            strSql.Append("INSERT INTO OrderInfor(");
            strSql.Append("UserId,X_ProId,X_ProName,StockNum,BuyNum,UnitPrice,OrderCode,TotalPrice,IsOther)");
            strSql.Append(" select UserId,X_ProId,X_ProName,StockNum,BuyNum,UnitPrice,@OrderCode,TotalPrice,IsOther from BasketDetail");
            strSql.AppendFormat(" where UserId=@UserId and IsSubmit=‘false‘ and IsInquiry=2 and IsExpired=0 and BasketDetailId in ({0})", Ids);
            SqlParameter[] parameters = {
                    new SqlParameter("@OrderCode", SqlDbType.NVarChar,100),
                    new SqlParameter("@UserId", SqlDbType.Int)
            };
            parameters[0].Value = OrderCode;
            parameters[1].Value = UserId;
            return parameters;
        }

internal static SqlParameter[] BuildUpdateParameter(int CouponId, int State, string OrderCode, ref StringBuilder strSql)
        {
            strSql = new StringBuilder();
            strSql.Append("update Coupon set");
            strSql.Append(" [State]=@State,OrderCode=@OrderCode");
            strSql.AppendFormat(" where ID={0}", CouponId);
            SqlParameter[] parameters = {
                    new SqlParameter("@State", SqlDbType.Int),
                    new SqlParameter("@OrderCode", SqlDbType.NVarChar,50)
            };
            parameters[0].Value = State;
            parameters[1].Value = OrderCode;
            return parameters;
        }
