NegotiateStream コンストラクター

定義

名前空間:

System.Net.Security

アセンブリ:

System.Net.Security.dll

NegotiateStream クラスの新しいインスタンスを初期化します。

オーバーロード

NegotiateStream(Stream)	指定した Stream を使用して NegotiateStream クラスの新しいインスタンスを初期化します。
NegotiateStream(Stream, Boolean)	指定した Stream とストリームを閉じる動作を使用して、NegotiateStream クラスの新しいインスタンスを初期化します。

注釈

指定した NegotiateStream ストリームが を閉じないようにするには、 コンストラクターを NegotiateStream(Stream, Boolean) 使用します。

例

次のコード例では、このコンストラクターの呼び出しを示します。

// 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)

ソース:

NegotiateStream.cs

指定した Stream とストリームを閉じる動作を使用して、NegotiateStream クラスの新しいインスタンスを初期化します。

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)

パラメーター

innerStream

Stream

NegotiateStream がデータの送受信に使用する Stream オブジェクト。

leaveInnerStreamOpen

Boolean

この NegotiateStream を閉じても、innerStream が影響を受けないことを示す場合は true。この NegotiateStream を閉じると、innerStream も閉じられることを示す場合は false。

例外

ArgumentNullException

innerStream が nullです。

または

innerStream と Null が等価です。

例

次の例では、このコンストラクターの呼び出しを示します。 このコード例は、NegotiateStream クラスのために提供されている大規模な例の一部です。

// 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)

注釈

パラメーターに を指定trueすると、 をNegotiateStream閉じるとストリームに影響innerStreamしません。不要になったら明示的に閉じるinnerStream必要leaveStreamOpenがあります。
