{{Quickfixn}} Question: Creating/populating a FIX message from a string - tag order problem

[Grant Birchmeier]

I see the problem.  You're calling Message's FromString method, instead of
MarketDataRequest's FromString.

Change your first line to this:

*QuickFix.FIX44.MarketDataRequest​* message =
​  ​
new QuickFix.FIX44.MarketDataRequest();


(Alternately you could, and probably should, just use *var* instead.)


That will cause message to call the right version of FromString().
