Keterangan

Stop menutup listener. Setiap permintaan koneksi yang tidak diterima dalam antrean akan hilang. Host jarak jauh yang menunggu koneksi diterima akan melemparkan SocketException. Anda bertanggung jawab untuk menutup koneksi yang anda terima secara terpisah.

Catatan

Anggota ini mengeluarkan informasi pelacakan saat Anda mengaktifkan pelacakan jaringan di aplikasi Anda. Untuk informasi selengkapnya, lihat Pelacakan Jaringan di .NET Framework.

Catatan Bagi Pemanggil

Metode ini Stop() juga menutup yang mendasar Socket, dan membuat yang baru Socket untuk TcpListener. Jika Anda mengatur properti apa pun pada yang mendasar Socket sebelum memanggil metode , properti tersebut Stop() tidak akan dibawa ke yang baru Socket.
