TcpListener.Stop メソッド
リスナを閉じます。 名前空間: System.Net.Sockets
アセンブリ: System (system.dll 内)
構文
例外
解説
呼び出し時の注意 また、Stop メソッドは、基になる Socket を閉じて、TcpListener の新しい Socket を作成します。Stop メソッドを呼び出す前に、基になる Socket のいずれかのプロパティを設定すると、それらのプロパティは新しい Socket には引き継がれません。 使用例

アセンブリ: System (system.dll 内)
構文例外解説Stop は、リスナを閉じます。キュー内で受け取られなかった接続要求はすべて失われます。接続の受け取りを待機していたリモート ホストは、SocketException をスローします。受け取った接続は、1 つずつ終了させる必要があります。
