Reading copyright character from file with StreamReader

[Ed West]

Hi,

I am trying to read a file, make changes, and write it to a new file.
The original file has the copyright character © which is ascii 169 I
believe, which is more than 7 bits. I am using typical StreamReader
object to read in the file, but it is not getting it correctly. If I
make the encoding type Ascii, it turns it into a question mark. If I
use UTF7 or UTF8, it ignores it. Unicode was jibberish. Any ideas?
Here is the file I am reading,
VersionLegalCop yright="©2005 All rights reserved."

and here is the code

StreamReader sr = null;
StreamWriter sw = null;
sr = new StreamReader(pr ojectFile, Encoding.ASCII) ;
sw = new StreamWriter(te mpProjectFile, false, Encoding.ASCII) ;
string line = String.Empty;

while ((line = sr.ReadLine()) != null)
{
// TODO: with regex's !!!
if (line.IndexOf(" ...") > 0)
sw.WriteLine("s omething");
else if ....
..
..
..
else
sw.WriteLine(li ne);
}
sw.Close();
sr.Close();

Thanks,

Ed

Do you happen to know what Codepage the file is encoded with? I would guess
Windows-1252(Latin I), so take a shot at using the encoding created by:

Encoding.GetEnc oding(1252);

There's no such thing as "ASCII 169" - ASCII doesn't have any values
over 127.

You can't just guess at the encoding - you need to know what it is. It
may well be ISO-8859-1 (code page 28591) or the default encoding for
the platform (Encoding.Defau lt) but you should understand what's
generating the file, and what encoding it will have used.

Jon and Daniel,

Thanks for the reply....

The file is actually a VB project file (*.vbp). I am automating
changing the build numbers, etc. Anyway, Encoding.GetEnc oding(1252)
seemed to work.

Thanks again..
