Receive a 32-bit Integer from a Socket
See more Socket/SSL/TLS Examples
Demonstrates Socket.ReceiveInt32, which reads exactly four bytes as a signed 32-bit integer and stores the result in the ReceivedInt property. Byte order is 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.
