Receive Text up to a Matching Sequence

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveUntilMatch, which receives bytes until an exact byte sequence is found. The match string is encoded using StringCharset and compared byte-for-byte.

Background. The comparison is case-sensitive with no Unicode normalization. This is useful for reading a message that ends with an application-defined marker delimiting the end of a response.
