Byte array to string without character conversion?

I need to search through a binary file to find a specific string and then
replace it with another string. However the
System.Text.Encoding.ASCII.GetString method i originally used seems to do
some character conversion. I also tried using UTF7-8 and Unicode
conversions, but the output is still converted. How do i get past this?

Thanks in advance,

ASCII = 7bit = characters 0 - 127 only

Which character encoding has been used to write into the file? You'd have to
know this first. If 1 character = 1 byte it's probably ANSI encoding
(System.Text.Encoding.Default).

Well, i just want the output to be exactly the same as the input. 0xFF =
0xFF and 0x7F = 0x7F and so on. I also tried the default encoding, but it
didn't work either. Any other suggestions?

You may want to use 'Encoding.Default' to read the file with the
currently used codepage.

Sorry - you're both right. I overlooked a spot where i did the conversion
once more.
Thanks alot.

Could you please show an example how you read/convert/display chars?
If you want to convert to Char/String, you must know the source
encoding because the byte value(s) must be converted to Unicode as
Chars are always Unicode encoded.
