[Quickfix-developers] weird code

[azmat <mr...@gm...>]

All,
I am nicely moving along creating my first ever FIX app and would like to
thank everyone in helping me with this journey.  I am now able to send
market data messages, however have problems with the Snapshot / Full Refresh
messages that are returned.  

This is what I wrote.  I based it off of what was written in the
documentation
(http://quickfixengine.org/quickfix/doc/html/csharp/repeating_groups_2.html)

            int iGroup = Int32.Parse(mdsfr.get(new
NoMDEntries()).ToString());
            QuickFix42.MarketDataSnapshotFullRefresh.NoMDEntries mdGroup =
new QuickFix42.MarketDataSnapshotFullRefresh.NoMDEntries();
            MDEntryType entryType = new MDEntryType();
            MDEntryPx entryPrice = new MDEntryPx();
            MDEntrySize entrySize = new MDEntrySize();

            for(uint i=0; i<iGroup; i++)
           { 
                mdsfr.getGroup(i, mdGroup); // what does this line do??

                if (mdGroup.get(new MDEntryType()).ToString() == "0") //bid
                {
                    MarketDepthData md = new
MarketDepthData(Int32.Parse(mdGroup.get(new MDEntrySize()).ToString()),
mdGroup.get(new MDEntryPx()).ToString());
                    mdupdate.bidList.Add(md.Price, md);

                }
                else if (mdGroup.get(new MDEntryType()).ToString() == "1")
//sell
                {
                    MarketDepthData md = new
MarketDepthData(Int32.Parse(mdGroup.get(new MDEntrySize()).ToString()),
mdGroup.get(new MDEntryPx()).ToString());
                    mdupdate.askList.Add(md.Price, md);
                }
                else //trade
                {
                    mdupdate.LastPrice = mdGroup.get(new
MDEntryPx()).ToString();
                    mdupdate.LastQty = Int32.Parse(mdGroup.get(new
MDEntrySize()).ToString());
                }

The line I think is "weird" is this one:

mdsfr.getGroup(i, mdGroup); // what does this line do??

The code compiles fine, but I have other issues in my app that don't let me
run it.  By the way, mdsfr is a MarketDataSnapshotFullRefresh message.  Does
anyone have any suggestions as to how I could improve this?

thanks!
