Receive a String from a Socket
See more Socket/SSL/TLS Examples
Demonstrates Socket.ReceiveString, which receives text and decodes it using StringCharset. It returns the first nonempty decoded result rather than draining all available data.
Background. Text send and receive operations encode and decode bytes using the
StringCharset property. For plain ASCII or UTF-8 protocols, setting StringCharset to utf-8 is a safe default.Chilkat Android™ Downloads
