Receive Bytes as Encoded Text from a Socket

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveBytesENC, which receives one delivery of binary data and returns it encoded as text using a named encoding.

-- Important: See this note about string length limitations for strings returned by sp_OAMethod calls.
