Receive Text from a Socket into a StringBuilder
See more Socket/SSL/TLS Examples
Demonstrates Socket.ReceiveSb, which receives text, decodes it using StringCharset, and appends it to a StringBuilder.
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 Swift Downloads
