How do I remove new line in constant if I have a string like this

string st1 ="\abc\def";

I use string trim but it doesn't work.

string st2;
for (int i = 0; i<st1.Lenght; i++)
{
st2 = st1.trim("\n".ToCharArray());
}

any idea?
thanks

Trim only works on characters at the beginning and end of the string. You
want something like

st2 = st1.Replace("\n","");

That's not a valid string - \d isn't a valid escape sequence. It also
doesn't contain any newlines...

That won't compile either, for various reasons. It's also entirely
unclear what purpose you expect the loop to serve. In future, it would
be well worth you producing a short but complete example which can be
compiled so that people can see your problem more clearly. See
http://www.pobox.com/~skeet/csharp/complete.html for details of
what I mean by that.

In this case, I believe your problem is that Trim only looks at the
start and end of the string. You should use Replace to replace all
occurrences.
 
Sorry for the unclear.

Problem is, I read in an mac address as an string "0040840c0290"
when I convert this into byte and it gave me 12 bytes by using :

byte [] buffer = Encoding.ASCII.GetBytes(this.Source.text);

But I'm only allow to store the mac address into 6 bytes.
[FieldOffset(0)] byte [] mac_add; //6 bytes
[FieldOffset(6)] byte [] ether_type; // 2 bytes
........

Well, it's not at all clear to me how that's related to your original
question, but it seems to me that you've got a hex string with 6 bytes
encoded there, which presumably needs to go in mac_add, and I'm not
sure about ether_type...
