Hi everybody, I'm trying to create some text files in c#. I have not to
put the encoding preamble bytes at the beginning of the files, 'cause
the unix software that reads my files gets some troubles with the
preamble.
How cna i do that?I know that using StreamWriter will alwais generate
those bytes...
Thanks

No, it will only generate the preamble if you use an encoding which
includes the preamble. If you don't specify the encoding, StreamWriter
uses a UTF-8 encoding which doesn't include the preamble. If for
whatever reason you need to specify the encoding, you can create a new
instance of UTF8Encoding which doesn't include the preamble - just use
new UTF8Encoding(false)

If you want to use the existing framework code you can simply derive
from the class and override GetPreamble to return a zero length array
(new byte[0])

You don't need to do that though - both of the built-in encodings which
can generate preambles (Unicode and UTF-8) have constructors which let
you tell the new instance not to generate a preamble.

Ahh, that is useful. Thanks for pointing it out.
