怎么用前台脚本输出....

public static List<Register> suiji()
            {
                List<Register> result = new List<Register>();

                string sql = "select top 19 * from Register order by NEWID()";
                try
                {
                    SqlDataReader reader = SqlHelper.ExecuteReader(SqlHelper.AppConnectionString, CommandType.Text, sql, null);
                    Register register;
                    while (reader.Read())
                    {
                        register = new Register(reader);
                        result.Add(register);
                    }

                    if (result.Count > 0)
                    {
                        reader.Close();
                        return result;
                    }
                    else
