Receive a 16-bit Integer from a Socket

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveInt16, which reads exactly two bytes as a 16-bit integer and stores the result in the ReceivedInt property. Byte order and signedness are selectable.

Background. Fixed-size integers and length prefixes are common building blocks for application-defined binary protocols. Byte order is selectable, with big-endian being network byte order.
