Примеры

В следующем примере кода демонстрируется вызов этого конструктора.

 // Establish the remote endpoint for the socket.
 // For this example, use the local machine.

 IPAddress ipAddress = ipHostInfo.AddressList[0];
 // Client and server use port 11000.
 IPEndPoint remoteEP = new IPEndPoint(ipAddress,11000);
 // Create a TCP/IP socket.
TcpClient client = new TcpClient();
 // Connect the socket to the remote endpoint.
 client.Connect(remoteEP);
 Console.WriteLine("Client connected to {0}.",
     remoteEP.ToString());
 // Ensure the client does not close when there is
 // still data to be sent to the server.
 client.LingerState = (new LingerOption(true,0));
 // Request authentication.
 NetworkStream clientStream = client.GetStream();
 NegotiateStream authStream = new NegotiateStream(clientStream);
 // Request authentication for the client only (no mutual authentication).
 // Authenicate using the client's default credetials.
 // Permit the server to impersonate the client to access resources on the server only.
 // Request that data be transmitted using encryption and data signing.

Примеры

В следующем примере показано, как вызвать этот конструктор. Этот пример кода является частью более крупного примера, предоставленного для NegotiateStream класса.

// Establish the remote endpoint for the socket.
// For this example, use the local machine.
IPHostEntry ipHostInfo = Dns.GetHostEntry("localhost");
IPAddress ipAddress = ipHostInfo.AddressList[0];
// Client and server use port 11000.
IPEndPoint remoteEP = new IPEndPoint(ipAddress, 11000);
// Create a TCP/IP socket.
client = new TcpClient();
// Connect the socket to the remote endpoint.
client.Connect(remoteEP);
Console.WriteLine("Client connected to {0}.", remoteEP.ToString());
// Ensure the client does not close when there is
// still data to be sent to the server.
client.LingerState = new LingerOption(true, 0);
// Request authentication.
NetworkStream clientStream = client.GetStream();
NegotiateStream authStream = new NegotiateStream(clientStream, false);

' Establish the remote endpoint for the socket.
' For this example, use the local machine.
Dim ipHostInfo = Dns.GetHostEntry("localhost")
Dim ipAddress = ipHostInfo.AddressList(0)

' Client and server use port 11000. 
Dim remoteEP As New IPEndPoint(ipAddress, 11000)

' Create a TCP/IP socket.
client = New TcpClient()

' Connect the socket to the remote endpoint.
client.Connect(remoteEP)
Console.WriteLine("Client connected to {0}.", remoteEP.ToString())

' Ensure the client does not close when there is 
' still data to be sent to the server.

' Request authentication.
Dim clientStream = client.GetStream()
Dim authStream As New NegotiateStream(clientStream, False)

Комментарии

При указании true параметра leaveStreamOpen закрытие NegotiateStream не влияет на innerStream поток; необходимо явно закрыть innerStream , если он больше не нужен.
