NegotiateStream Constructor (Stream^)

 

Initializes a new instance of the NegotiateStream class using the specified Stream.

Namespace:   System.Net.Security
Assembly:  System (in System.dll)

public:
NegotiateStream(
	Stream^ innerStream
)

Parameters

innerStream
Type: System.IO::Stream^

A Stream object used by the NegotiateStream for sending and receiving data.

The following code example demonstrates calling this constructor.

// 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 );
