Receive Text up to a Delimiter Byte
See more Socket/SSL/TLS Examples
Demonstrates Socket.ReceiveStringUntilByte, which receives bytes until a specific raw byte value is found, then decodes the preceding bytes using StringCharset. The delimiter is excluded from the returned string.
Background. The delimiter search is purely byte-oriented and does not recognize character boundaries. A common delimiter is the linefeed byte (decimal 10).
