我们要求按照设置的顺序发送消息的前 3 个字段，即 QuoteReqID、OnBehalfOfCompID、Account。但是，当它们添加到消息中时，它们会按数字升序重新排序，即 Account、OnBehalfOfCompID、QuoteReqID。通过组，我们可以定义字段顺序，但我看不到为消息执行此操作的选项。有谁知道我们如何实现这一目标？

            var message = new QuoteRequest();
            int[] fieldOrder = new[] {Tags.Currency, Tags.Symbol, Tags.SecurityType, Tags.CFICode, Tags.NoLegs, Tags.LegQty, Tags.LegFutSettDate, Tags.LegSecuritySubType};

            message.SetField(new QuoteReqID(stream.QuoteRequestId));
            message.SetField(new OnBehalfOfCompID(_compId));
            message.SetField(new Account(_accountId));
            var group = new Group(Tags.NoRelatedSym, 0, fieldOrder);
            group.SetField(new Currency(stream.Ccy));
            group.SetField(new Symbol(stream.Ccy1 + "/" + stream.Ccy2));
            group.SetField(new SecurityType("FOR"));
            group.SetField(new CFICode("FORWARD"));
            group.SetField(new NoLegs(1));
            group.SetField(new LegQty(stream.Amount));
            group.SetField(new LegFutSettDate(stream.FutSettDate));
            group.SetField(new LegSecuritySubType("TOD"));

            message.AddGroup(group);

            QuickFix.Session.SendToTarget(message, _ratesSession.SessionId);
