Andrea,

string text = (new System.Text.ASCIIEncoding()).GetString(byte[]);

How are the characters encoded in the byte array? You need to examine the
System.Text.Encoding class and its related classes:
System.Text.ASCIIEncoding, System.Text.UnicodeEncoding. Here's a basic
example, if the byte array is ASCII:

System.Text.ASCIIEncoding AE = new System.Text.ASCIIEncoding();
byte[] ByteArray = { 69, 110, 99, 111, 100, 105, 110, 103, 32, 83, 116,
114, 105, 110, 103, 46 };
char[] CharArray = AE.GetChars(ByteArray);
string s = new string(CharArray);
MessageBox.Show(s);

Encoding.ASCII.GetString(byteArray);

char[] CharArray = AE.GetChars(ByteArray);
string s = new string(CharArray);
MessageBox.Show(s);

Or, slightly more simply:

MessageBox.Show (Encoding.ASCII.GetString(bytes));

There's no need to create a new ASCIIEncoding, or to get a character
array and then create a string from that.

That's what I get for cutting and pasting from MSDN

Could you let me know which MSDN page it is? I'm more than happy to
write an email suggesting a change...

The article places an emphasis on coverting to chars, so the methodology may
be appropriate (if roundabout).

That much is fine, but there's no excuse for creating a new
ASCIIEncoding instance.
