Hello All,

I want to convert byte[] into string, it working correctly with following line.

byte[] byArr= new byte[10];

string ascii =  Encoding.ASCII.GetString(byArr);

But when the char's int value is greater than 127 (i.e extended ASCII char), then i am getting string with wrong character as compare to ASCII characters. I tried with many encoder classes, but each time i am getting different values i.e. which is not same as values in the ASCII table.

Please help me to solve this issue.

Thanks.

It's better to use base64 encoding : Convert.ToBase64String Method (Byte[])[^]

Byte 189 represents a "½" in iso-8859-1 (aka "Latin-1"), so the following is maybe what you want:

C#

var e = Encoding.GetEncoding("iso-8859-1");
var s = e.GetString(new byte[] { 189 });

All strings and chars in .NET are UTF-16 encoded, so you need to use an encoder/decoder to convert anything else, sometimes this is defaulted (e.g. UTF-8 for FileStream instances) but good practice is to always specify.

You will need some form of implicit or (better) explicit metadata to supply you with the information about which encoding.
