[Quickfix-developers] How do I change the field of a message from the .net api?

[Wilhelm T. <th...@cu...>]

 hello

Happy new year to all!

I'm using the .net api

I'm working on a gateway, I receive a message from my acceptor function

fromApp(Message message, SessionID sessionID)

1) I basically need to change some fields from this message and forward back
the message to my Initiator

I'm basically doing this:

message.removeField((int)49);
message.removeField(56);
Console.Out.WriteLine(">>>> m=" + message.ToString());
message.setField(49, "MAXP2"); // SenderCompID
message.setField(56, "MAX2PRICE"); // TargetCompID
Console.Out.WriteLine(">>>> m=" + message.ToString());
message.setString(49, "MAXP2"); // SenderCompID
message.setString(56, "MAX2PRICE"); // TargetCompID
Console.Out.WriteLine(">>>> m=" + message.ToString());


but when I call some ,remove, replace, setField, setString, nothing change
the fields 49 and 56?
2) I also try to loop over the fields and create a new message but I do not
get the correct field

System.Collections.IEnumerator enum_ = message.GetEnumerator();
QuickFix.Field key = null;
while(enum_.MoveNext()){
  key = (Field)enum_.Current;
  message2.setField(key.getField(), (string)key.getObject());
}

Here is what I see once this while execute:

+  message {8=FIX.4.2
9=225
35=V
34=2
49=BLABLA
52=20090109-03:49:01.464
56=GATEWAY146=1
55=6E

48=6E012008090000003232
167=FUT
200=200809
202=0
207=TTSIM
262=1/8/2009

263=1
264=10
265=1
266=Y
267=3
269=0
269=1
269=2
10=192
}
QuickFix.Message
{QuickFix42.MarketDataRequest}

+  message2 {8=FIX.4.2
9=69
35=V
146=1
262=1/8/2009 7:49:01
PM172
263=1
264=10
265=1
266=Y
267=3
10=251
} QuickFix42.MarketDataRequest

Which is weird as message2 isn't at all like message?

Any idea why?

thanks a lot for your help
