The SelectMode enumeration defines the polling modes that can be passed to the Socket..::..Poll method. Use the SelectRead value to determine if a listening Socket has incoming connection requests. Use the SelectWrite value to determine if a Socket is writeable. Use the SelectError value to determine if there is an error condition present on the Socket. For explanations of writeability, readability, and the presence of error conditions, see the Socket..::..Poll method.
