Send a 16-bit Integer over a Socket
See more Socket/SSL/TLS Examples
Demonstrates Socket.SendInt16, which sends the low 16 bits of a value as a two-byte integer in the selected byte order.
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.
