範例
下列程式代碼範例示範如何使用 Stop 方法來關閉基礎 Socket。

備註
Stop 關閉接聽程式。 佇列中任何未接受的連接要求都會遺失。 等候接受連線的遠端主機會擲回 SocketException。 您必須負責個別關閉已接受的連線。
注意
在應用程式中啟用網路追蹤時，這個成員會輸出追蹤資訊。 如需詳細資訊，請參閱 .NET Framework 中的網路追蹤。
給呼叫者的注意事項
方法 Stop() 也會關閉基礎 Socket，並為 建立新的 SocketTcpListener。 如果您在呼叫 Stop() 方法之前，在基礎Socket上設定任何屬性，這些屬性將不會繼續傳送至新的 Socket。
