The Socket class uses the ProtocolType enumeration to inform the Windows Sockets API of the requested protocol. Low-level driver software for the requested protocol must be present on the computer for the Socket to be created successfully.

The following example demonstrates how to use ProtocolType to instantiate a Socket.

No code example is currently available or this language may not be supported.
