DAL层修改sql表数据

组长写的，DAL层Update

        //编辑
        public int Update(Dictionary<string, object> par, long uid)
        {
            if (par.Count == 0) return 0;
            StringBuilder Sql = new StringBuilder();
            Sql.Append("UPDATE uc_user SET ");
            SqlParameter[] pars = new SqlParameter[par.Count + 1];
            string[] fields = new string[par.Count];
            int index = 0;
            foreach (string name in par.Keys)
            {
                Sql.AppendFormat("[" + name + "] =@p_{0},", index);
                pars[index] = new SqlParameter("@p_" + index.ToString(), par[name]);
                index++;
            }
            Sql.Remove(Sql.Length - 1, 1);
            Sql.Append(" WHERE ");
            Sql.Append("[UID] = @p_" + index.ToString());
            pars[index] = new SqlParameter("@p_" + index.ToString(), uid);
            index++;
            return SqlHelper.ExecuteNonQuery(ConnectionString, CommandType.Text, Sql.ToString(), pars);
        }

修改用户名，BLL层只需要传入对应的密码

        public static int Update(Dictionary<string, object> par, long AUID)
        {
            return dal.Update(par, AUID);
        }

        public static int EditPwd(string Pwd, long Auid)
        {
            Dictionary<string, object> dic = new Dictionary<string, object>();
            dic.Add("UserPassword", Utils.MD5(Pwd));
            return Update(dic, Auid);
        }

然后web层调用就行

BLL.Uc.UserB2B.EditPwd(newpwd, CurrentUser.UID);

因为是字典循环调用，固传入修改的什么列，就修改什么列，条件自己定义，很灵活
