The following example uses this enumeration to set socket options.

// Specifies that send operations will time-out 
// if confirmation is not received within 1000 milliseconds.
s->SetSocketOption( SocketOptionLevel::Socket, SocketOptionName::SendTimeout, 1000 );

// Specifies that the Socket will linger for 10 seconds after Close is called.
LingerOption^ lingerOption = gcnew LingerOption( true,10 );

s->SetSocketOption( SocketOptionLevel::Socket, SocketOptionName::Linger, lingerOption );
