Socket類別會ProtocolType使用列舉來通知 Windows 通訊端 API 所要求的通訊協定。The Socket class uses the ProtocolType enumeration to inform the Windows Sockets API of the requested protocol. 電腦上必須要有要求之通訊協定的低層級驅動程式軟體, Socket才能成功建立。Low-level driver software for the requested protocol must be present on the computer for the Socket to be created successfully.
