byte[] to string conversion ...

[Jamie Risk]

This is the code snippet that I've come up to convert a byte[]
to string. Is there a best practiced method for such a conversion?

- Jamie

public static string ByteArrayToStri ng(byte[] array)
{
if (null == array || 0 == array.Length)
{
throw new NullReferenceEx ception();
return null;
}
else
{
Encoding ascii = Encoding.ASCII;
char[] asciiChars =
new char[ascii.GetCharCo unt(array, 0, array.Length)];
string str = null;

ascii.GetChars( array, 0, array.Length, asciiChars, 0);

foreach (string s in (new string(asciiCha rs)).Split('\n' ))
{
if (str != null) str += Environment.New Line;
str += s.Trim();
}
return str;
}
}

Hi Jamie,

System.Encoding has already the appropriate methods:

public static string ByteArrayToStri ng(byte[] array)
{
if (array == null)
{
throw new ArgumentNullExc eption("array") ;
}
return Encoding.ASCII. GetString(array );
}

public static byte[] StringToByteArr ay(string value)
{
if (value == null)
{
throw new ArgumentNullExc eption("array") ;
}
return Encoding.ASCII. GetBytes(value) ;
}

Best Regards,

Well, for a start the easiest way of doing the first part of your work
is to call Encoding.ASCII. GetString(array ) instead of going through
GetCharCount, GetChars and new string(...).

Now, it looks like the rest of your conversion is to trim each line,
and then glue them back together using Environment.New Line - correct?

If so, I'd use String.Split to get the array, then call Trim on each
element, then call String.Join to join them back together again
afterwards.

By the way, I don't *believe* String.Split will ever return a null
element.

if (str != null) str += Environment.New Line;
str += s.Trim();
}
return str;
}
}

What does the code do that:

ascii.GetString (b)

or maybe

ascii.GetString (b).Replace(@"\ n", Environment.New Line)

does not ?

I guess it trim trailing space of lines, but is that really
needed.

If you need the trimming then maybe a simple for loop
copying from one byte array to another and a ascii.GetString
on the new array.

"zeros" will get you in trouble. Base64 is probably what you are looking for
if you intend to transfer a byte array as a string.
