public:
 override void Write(cli::array <System::Byte> ^ buffer, int offset, int count);

public override void Write(byte[] buffer, int offset, int count);

範例

以下程式碼範例示範如何寫入 NegotiateStream。

    public static void Main(String[] args)
    {
        // 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);
        DisplayAuthenticationProperties(authStream);
        DisplayStreamProperties(authStream);
        if (authStream.CanWrite)
        {
             // Encode the test data into a byte array.
            byte[] message = System.Text.Encoding.UTF8.GetBytes("Hello from the client.");
            authStream.Write(message, 0, message.Length);
            authStream.Flush();
            Console.WriteLine("Sent {0} bytes.", message.Length);
        }
        // Close the client connection.
        authStream.Close();
        Console.WriteLine("Client closed.");
}

備註

若啟用加密、簽名或加密加簽名，此方法會從緩衝區讀取資料，進行加密、簽署或加密並簽署，並透過底層串流傳輸。 若未使用資料加密或簽章等安全服務，此方法會 Write 呼叫底層串流。

此方法在寫入操作完成時會阻塞。 為了防止操作完成時阻塞，請使用此 WriteAsync 方法。

在成功驗證之前，你不能呼叫這個方法。 要驗證，請呼叫其中一個 AuthenticateAsClient、 AuthenticateAsClientAsync、 BeginAuthenticateAsClient、 AuthenticateAsServerAuthenticateAsServerAsync、 或 BeginAuthenticateAsServer 方法。

此 NegotiateStream 類別不支援多個同時寫入操作。 如果你嘗試在另一個寫入操作同時啟動，而另一個寫入操作已經在同一串流 NotSupportedException 上執行，將會拋出異常。
