For converting from string to bytes array and from bytes array to string you should use pair methods, that are using the same encoding, like in the next examples:

1.From string to byte array:

C#

byte[] resultArray = System.Text.Encoding.UTF8.GetBytes(stringValue);

2.From byte array to string:

C#

string stringResult = System.Text.Encoding.UTF8.GetString(byteArray);
