找不到修复标签，何时出现

Question

当我尝试解析我的修复消息时，它会失败，说"未找到字段134"。但是，当我在调试器中看到消息时，标签134存在。我检查了我的数据字典，似乎还不错。

以下是我的代码。

var QuoteGroup =
                new QuickFix.FIX44.MassQuote.NoQuoteSetsGroup();
            msg.GetGroup(1, QuoteGroup);
            //bid group
            bidQty = Int32.Parse(QuoteGroup.GetString(134));
            string offerQty1 = QuoteGroup.GetField(135);
            string bidPriceStr = QuoteGroup.GetField(tag: 188);
            float.TryParse(bidPriceStr, out bidPrice);

修复消息：20170224-20：55：27.640：8 = fix.4.4 | 9 = 132 | 35 = i | 34 = 2 | 49 = XCD12 | 52 = 20170224-20：55：30.274 | 30.274 | 56 = Q051 |1 | 302 = avg | 295 = 1 | 299 = 0 | 134 = 2000000 | 135 = 2000000 | 188 = 1.24556 | 190 = 1.24561 | 10 = 027 |

请让我知道，如果您需要更多详细信息。

Answer 1

您正在尝试从引号组中提取134，而不是嵌套在其中的引号。

您的消息，根据组缩进：

296=1 NoQuoteSets
  302=AVG
  295=1 NoQuoteEntries
    299=0
    134=2000000
    135=2000000
    188=1.24556
    190=1.24561

您的代码应该是这样的：

        var QuoteGroup =
            new QuickFix.FIX44.MassQuote.NoQuoteSetsGroup();
        msg.GetGroup(1, QuoteGroup);
        var QuoteEntry =
            new QuickFix.FIX44.MassQuote.NoQuoteSetsGroup.NoQuoteEntriesGroup();
        QuoteEntry.GetGroup(1, QuoteEntry);
        bidQty = Int32.Parse(QuoteEntry.GetString(134));
