버튼을 이용 연결 및 해제를 하려고 하는데요...
해제를 위해 버튼을 눌렀을때 소켓을 close() ( listen.close(); )하면..

StartAccept () 계속 호출 되는데요... 원래 이런건지요?? 아니면 소스가 잘못된건지요....
ObjectDisposedException 에러가 호출 되네요..
StartAccept () {
...
...
 bool willRaiseEvent = listenSocket.AcceptAsync(acceptEventArg); // 에러 부분...
...
...
...
}

조언좀 해주시면 감사하겠습니다...
참고로..
https://msdn.microsoft.com/ko-kr/library/system.net.sockets.socketasynceventargs(v=vs.110).aspx
예제를 참고하면서 구현하고 있습니다..
