NegotiateStream Constructeurs

Définition

Espace de noms:

System.Net.Security

Assembly:

System.Net.Security.dll

Initialise une nouvelle instance de la classe NegotiateStream.

Surcharges

NegotiateStream(Stream)	Initialise une nouvelle instance de la classe NegotiateStream à l'aide du Stream spécifié.
NegotiateStream(Stream, Boolean)	Initialise une nouvelle instance de la classe NegotiateStream en utilisant le Stream et le comportement de clôture de flux spécifiés.

Remarques

Pour empêcher la NegotiateStream fermeture du flux que vous fournissez, utilisez le NegotiateStream(Stream, Boolean) constructeur .

Exemples

L’exemple de code suivant illustre l’appel de ce constructeur.

// Establish the remote endpoint for the socket.
// For this example, use the local machine.
IPHostEntry^ ipHostInfo = Dns::GetHostEntry( Dns::GetHostName() );
IPAddress^ ipAddress = ipHostInfo->AddressList[ 0 ];

// Client and server use port 11000. 
IPEndPoint^ remoteEP = gcnew IPEndPoint( ipAddress,11000 );

// Create a TCP/IP socket.
TcpClient^ client = gcnew TcpClient;

// Connect the socket to the remote endpoint.
client->Connect( remoteEP );
Console::WriteLine( L"Client connected to {0}.", remoteEP );

// Ensure the client does not close when there is 
// still data to be sent to the server.
client->LingerState = (gcnew LingerOption( true,0 ));

// Request authentication.
NetworkStream^ clientStream = client->GetStream();
NegotiateStream^ authStream = gcnew 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.
authStream->AuthenticateAsClient( dynamic_cast<NetworkCredential^>(CredentialCache::DefaultCredentials), 
       L"", 
       ProtectionLevel::EncryptAndSign, 
       TokenImpersonationLevel::Impersonation );

 // Establish the remote endpoint for the socket.
 // For this example, use the local machine.
 IPHostEntry ipHostInfo = Dns.GetHostEntry(Dns.GetHostName());
 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.
 authStream.AuthenticateAsClient(
      (NetworkCredential) CredentialCache.DefaultCredentials,
      "",
      ProtectionLevel.EncryptAndSign,
      TokenImpersonationLevel.Impersonation);

NegotiateStream(Stream, Boolean)

Source:

NegotiateStream.cs

Initialise une nouvelle instance de la classe NegotiateStream en utilisant le Stream et le comportement de clôture de flux spécifiés.

public:
 NegotiateStream(System::IO::Stream ^ innerStream, bool leaveInnerStreamOpen);

public NegotiateStream (System.IO.Stream innerStream, bool leaveInnerStreamOpen);

new System.Net.Security.NegotiateStream : System.IO.Stream * bool -> System.Net.Security.NegotiateStream

Public Sub New (innerStream As Stream, leaveInnerStreamOpen As Boolean)

Paramètres

innerStream

Stream

Objet Stream utilisé par NegotiateStream pour envoyer et recevoir des données.

leaveInnerStreamOpen

Boolean

true pour indiquer que la fermeture de ce NegotiateStream n'a aucun effet sur innerStream ; false pour indiquer que la fermeture de ce NegotiateStream ferme également innerStream.

Exceptions

ArgumentNullException

innerStream a la valeur null.

- ou -

innerStream est égal à Null.

Exemples

L’exemple suivant illustre l’appel de ce constructeur. Cet exemple de code fait partie d’un exemple plus grand fourni pour la NegotiateStream classe .

// Establish the remote endpoint for the socket.
// For this example, use the local machine.
IPHostEntry^ ipHostInfo = Dns::GetHostEntry( Dns::GetHostName() );
IPAddress^ ipAddress = ipHostInfo->AddressList[ 0 ];

// Client and server use port 11000. 
IPEndPoint^ remoteEP = gcnew IPEndPoint( ipAddress,11000 );

// Create a TCP/IP socket.
client = gcnew TcpClient;

// Connect the socket to the remote endpoint.
client->Connect( remoteEP );
Console::WriteLine( L"Client connected to {0}.", remoteEP );

// Ensure the client does not close when there is 
// still data to be sent to the server.
client->LingerState = (gcnew LingerOption( true,0 ));

// Request authentication.
NetworkStream^ clientStream = client->GetStream();
NegotiateStream^ authStream = gcnew NegotiateStream( clientStream,false );

// 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.
client.LingerState = (New LingerOption(True, 0))

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

Remarques

Lorsque vous spécifiez true pour le paramètre, la leaveStreamOpen fermeture du NegotiateStream n’a aucun effet sur le innerStream flux ; vous devez fermer innerStream explicitement lorsque vous n’en avez plus besoin.
