Hello,

a simple question (if you know the answer) ... how to convert from and array
of bytes to a string (and viceversa). I haven't the conversion to be simple
... but even using the Convert or the Encoding class I seem to be having
trouble accomplishing it.

I would use Encoding.Default.GetBytes for the String->Byte [] conversion

and Encoding.Default.GetString for the Byte []->String conversion

You need to know what encoding to use.

See http://www.pobox.com/~skeet/csharp/unicode.html for an explanation
of what it's all about.

That's only applicable if you *do* want to use the default encoding for
the current computer though - which in many cases isn't the right
choice. Guessing isn't a good idea with character encodings.
 
Hehe.

Yes, i know that.
It was an _example_.

System.Byte[] inputData;
string inputstream = System.Text.Encoding.ASCII.GetString(inputData) ;

Thats it !! :)

Again, that's it if Encoding.ASCII *happens* to be the encoding you
want.

The code is going to be simple virtually whatever encoding you're
interested in, but working out which encoding is the right one to use
is very important - much more so than your post implied.
