Hi all!
I have a major problem. I need to write an textfile with 1 b per letter. But
it should be able to handle swedish letters to (åäö).
Is it possible to use 8 b ASCII for this?
This file is used by an sms application and cannot be in another format.

There's no such thing as "8 bit ASCII" (assuming that's what you meant
by "b").

You need to find out *exactly* what encoding will be used. There are
various 8 bit character sets which are compatible with ASCII in the
range 0-127, but which are incompatible with each other above 127. If
you can find out which of those your app needs to output, it should be
easy to find the appropriate Encoding to give to your StreamWriter.

Hi Marre,
I believe Swedish uses the standard European characterset ISO-8859-1, or you could use ISO-8859-15 which is the nordic set (no å and æ in 8859-1, so I would recomment the latter)
System.IO.StreamWriter sw = new System.IO.StreamWriter(path);
sw.Encoding = System.Text.Encoding.GetEncoding("ISO-8859-15");

You could also use cp1252, which supports Swedish well.
Or even better Unicode, which supports everything.

Well, Unicode wouldn't be 8-bit, now would it :P

Well, I wouldn't say it's an "8-bit encoding" in the normal sense of
the phrase...
Not every character in the set (in fact, very few!) can be represented
as a single byte.

Yes -- but Unicode covers a lot of ground. Attempts to do less lead to
corruption of text in the "lesser" code page, and I am reasonably certasin
that such corruption is never a good thing....

That's pretty much irrelevant when the encoding is fixed to start with
though, as the OP says it is. The best you can do is detect that you're
trying to write a character which isn't in the target character set,
and either throw an exception or write something else (eg '?').

Ok. Is it ASCII-8 then?
Well, I solved it by using this code:
char[] test = mailContent.ToCharArray();
System.Text.Encoding enc = System.Text.Encoding.GetEncoding("437");
System.Text.Encoder ence = enc.GetEncoder();
FileStream fsWriter = new FileStream(filePath + fileName,
System.IO.FileMode.Create);
byte[] bytes = new Byte[ence.GetByteCount(test,0, test.Length, true)];
ence.GetBytes(test, 0, test.Length, bytes, 0, true);
fsWriter.Write(bytes, 0, bytes.Length);

Is what "ASCII-8", exactly? Can't say I've heard of that before.
Well, I solved it by using this code:
char[] test = mailContent.ToCharArray();
System.Text.Encoding enc = System.Text.Encoding.GetEncoding("437");
System.Text.Encoder ence = enc.GetEncoder();
FileStream fsWriter = new FileStream(filePath + fileName, System.IO.FileMode.Create);
byte[] bytes = new Byte[ence.GetByteCount(test,0, test.Length, true)];
ence.GetBytes(test, 0, test.Length, bytes, 0, true);
fsWriter.Write(bytes, 0, bytes.Length);
Just using StreamReader with an encoding of Encoding.GetEncoding("437")
would be rather simpler. However, are you *really* sure it's code page
437? If you've got the wrong code page, you'll write out the wrong
characters sooner or later.

Well, as you might have noticed, I´m really a newbie here :) I looked at
this link: http://homepage.cs.uri.edu/faculty/w...pleteASCII.htm Just using StreamReader with an encoding of Encoding.GetEncoding("437") would be rather simpler. However, are you *really* sure it's code page 437? If you've got the wrong code page, you'll write out the wrong characters sooner or later.
Yes. According to those who have developed the app I´m 'talking' with, it´s
437.
It´s not that important if some character get wrong, but if it happends, I
will probably return to this newsgroup :)
Sorry for my quote-problem. Never thougt of that before.

Any page which claims ASCII has characters over 127 shouldn't be
trusted, I'm afraid... Just using StreamReader with an encoding of Encoding.GetEncoding("437") would be rather simpler. However, are you *really* sure it's code page 437?

Good. It's always nice when you don't have to guess :)

Righto.

No problem - thanks for fixing it.
