NegotiateStream Konstruktoren

Definition

Namespace:

System.Net.Security

Assembly:

System.Net.Security.dll

Initialisiert eine neue Instanz der NegotiateStream-Klasse.

Überlädt

NegotiateStream(Stream)	Initialisiert eine neue Instanz der NegotiateStream-Klasse mit dem angegebenen Stream.
NegotiateStream(Stream, Boolean)	Verwendet den angegebenen NegotiateStream und das Schlussverhalten des Streams zum Initialisieren einer neuen Instanz der Stream-Klasse.

Hinweise

Verwenden Sie den Konstruktor NegotiateStream(Stream, Boolean), um zu verhindern, dass der von Ihnen bereitgestellte Stream durch NegotiateStream geschlossen wird.

NegotiateStream(Stream)

Quelle:

NegotiateStream.cs

Initialisiert eine neue Instanz der NegotiateStream-Klasse mit dem angegebenen Stream.

public:
 NegotiateStream(System::IO::Stream ^ innerStream);

public NegotiateStream (System.IO.Stream innerStream);

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

Public Sub New (innerStream As Stream)

Parameter

innerStream

Stream

Ein Stream-Objekt, das von NegotiateStream zum Senden und Empfangen von Daten verwendet wird.

Beispiele

Im folgenden Codebeispiel wird das Aufrufen dieses Konstruktors veranschaulicht.

// 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)

Quelle:

NegotiateStream.cs

Verwendet den angegebenen NegotiateStream und das Schlussverhalten des Streams zum Initialisieren einer neuen Instanz der Stream-Klasse.

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)

Parameter

innerStream

Stream

Ein Stream-Objekt, das von NegotiateStream zum Senden und Empfangen von Daten verwendet wird.

leaveInnerStreamOpen

Boolean

true, um anzugeben, dass das Schließen dieses NegotiateStream keine Auswirkungen auf innerStream hat. false, um anzugeben, dass durch Schließen dieses NegotiateStream auch innerStream geschlossen wird.

Ausnahmen

ArgumentNullException

innerStream ist null.

- oder -

innerStream ist gleich Null.

Beispiele

Das folgende Beispiel veranschaulicht das Aufrufen dieses Konstruktors. Dieses Codebeispiel ist Teil eines größeren Beispiels, das für die NegotiateStream-Klasse bereitgestellt wird.

// 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)

Hinweise

Wenn Sie für den Parameter angebentrue, hat das Schließen von NegotiateStream keine Auswirkungen auf den innerStream Stream. Sie müssen explizit schließeninnerStream, wenn Sie ihn nicht mehr leaveStreamOpen benötigen.
