ADO.NET 插入数据的问题
怎么同时向多张表插入数据，我是像下面这样 一个方法插入一张表，有没有更简单的方法？
        public const string connstr = "server=.;database=test;Integrated Security=true";
        static void Main(string[] args)
        {
            InsertData1("s003", "d003", "HiTerminal", "ABCDEFG", "STB Device", "12345678");
            InsertData2("d003","InternetGatewayDevice.DeviceInfo.SoftwareVersion","1.0",0,2);
            Console.ReadLine();
        }

        public static void InsertData1(string sid,string Device_varID, string Manufacturer,string OUI,string ProductClass,string SerialNumber)
        {
            SqlConnection conn = new SqlConnection(connstr);
            string sqltext = "insert into  A  values (@sid,@Device_varID,@Manufacturer,@OUI,@ProductClass,@SerialNumber)";
            SqlCommand cmd = new SqlCommand(sqltext,conn);
            SqlParameter[] parameter = { new SqlParameter("@sid",sid),
                                           new SqlParameter("@Device_varID",Device_varID),
                                           new SqlParameter("@Manufacturer",Manufacturer),
                                           new SqlParameter("@OUI",OUI),
                                           new SqlParameter("@ProductClass",ProductClass),
                                           new SqlParameter("@SerialNumber",SerialNumber)
                                       };
            cmd.Parameters.AddRange(parameter);
            using (conn)
            {
