LingerOption^ lingerOption = gcnew LingerOption(true, 10);
s->SetSocketOption(SocketOptionLevel::Socket, SocketOptionName::Linger, lingerOption);

// The socket will linger for 10 seconds after Socket.Close is called.
var lingerOption = new LingerOption(true, 10);
s.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.Linger, lingerOption);

' The socket will linger for 10 seconds after Socket.Close is called.
Dim lingerOption As New LingerOption(True, 10)
s.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.Linger, lingerOption)

Remarks
