I have a Stream but at some point I need to convert byte array to string?
What is most efficient way to do that?

public override void Write(byte[] buffer, int offset, int count)

{

String sKey = new String((sbyte[])buffer,offset, count); -- does not
compile. Can not convert byte[] to sbyte[].

}

Thanks.

George.

Hi George,

Did you tried BitConverter.ToString( byte[] ) ?

Hope this help,

string s = Use System.Text.Encoding.ASCII.GetString (buffer);

You should use Encoding.GetString (byte[]) - but which encoding you
wish to use depends on the application. Is the data fundamentally text
data? If not, I would suggest not converting it into a string at all,
or using something like Base16 or Base64. If it is, you will hopefully
know the encoding.

See http://www.pobox.com/~skeet/csharp/unicode.html for more
information.

Sorry, Wrong answer

You can use ASCIIEncoding.GetString( byte[] ) for that.

Sorry for the first post

Cheers,

This one's easy. Just use a StreamReader.

System.IO.MemoryStream s = new MemoryStream(buffer, offset, count);
System.IO.StreamReader read = new StreamReader(s);
stsring sKey = read.ReadToEnd();

Hope this works for you.

Well, that's just as wrong if the data isn't originally in ASCII :)

It really depends what the data really *is*...

Thanks to everyone.
I am writing a filter for HttpResponse so my guess I should use
System.Text.Encoding.UTF8

And I can not use any other format since that filter looks for tokens (given
as strings) and substitutes them with special phrases. So somehow I need to
convert bytes back to the string to match it against tokens.

Thanks.
George.

Yikes, that seems a longwinded way of doing:

string sKey = Encoding.UTF8.GetString (buffer, offset, count);

:)

Hey, what can I say? I'd never heard of the System.Text.AsciiEncoding class
before.

Well, don't guess -- check it out ;-)

Encoding encoding = Response.ContentEncoding;
