How To Convert Received Bytes To String?

[Noreturn]

Hi friends, at an example i found in MSDN library, such a command is used to convert the received bytes to ASCII string;

data = Text::Encoding::ASCII->GetString( bytes, 0, i );

But my compiler can not build due to errors in this statement. I think this code is written for 2003 version and I use 2005, so there must be a new translating method just like many other changes... Can you help me about how to do this in version 2005. Thanks...
