NegotiateStream Konstruktor

Definisi

Ruang nama:

System.Net.Security

Rakitan:

System.Net.Security.dll

Menginisialisasi instans baru kelas NegotiateStream.

Overload

NegotiateStream(Stream)	Menginisialisasi instans NegotiateStream baru kelas menggunakan Stream.
NegotiateStream(Stream, Boolean)	Menginisialisasi instans NegotiateStream baru kelas menggunakan perilaku penutupan yang ditentukan Stream dan streaming.

Keterangan

Untuk mencegah NegotiateStream menutup aliran yang Anda berikan, gunakan NegotiateStream(Stream, Boolean) konstruktor.

NegotiateStream(Stream)

Sumber:

NegotiateStream.cs

Menginisialisasi instans NegotiateStream baru kelas menggunakan 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

Objek Stream yang NegotiateStream digunakan oleh untuk mengirim dan menerima data.

Contoh

Contoh kode berikut menunjukkan panggilan konstruktor ini.

// 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)

Sumber:

NegotiateStream.cs

Menginisialisasi instans NegotiateStream baru kelas menggunakan perilaku penutupan yang ditentukan Stream dan streaming.

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

Objek Stream yang NegotiateStream digunakan oleh untuk mengirim dan menerima data.

leaveInnerStreamOpen

Boolean

true untuk menunjukkan bahwa menutup ini NegotiateStream tidak berpengaruh pada innerStream; false untuk menunjukkan bahwa menutup ini NegotiateStream juga menutup innerStream.

Pengecualian

ArgumentNullException

innerStreamadalah null.

-atau-

innerStream sama dengan Null.

Contoh

Contoh berikut menunjukkan pemanggilan konstruktor ini. Contoh kode ini adalah bagian dari contoh yang lebih besar yang disediakan untuk NegotiateStream kelas .

// 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)

Keterangan

Ketika Anda menentukan true untuk leaveStreamOpen parameter , menutup NegotiateStream tidak berpengaruh pada innerStream aliran; Anda harus secara eksplisit menutup innerStream ketika Anda tidak lagi membutuhkannya.
