NegotiateStream.NegotiateStream(Stream, Boolean) Constructor

Initializes a new instance of the NegotiateStream class using the specified Stream and stream closure behavior.

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

public NegotiateStream (
	Stream innerStream,
	bool leaveInnerStreamOpen
public NegotiateStream (
	Stream innerStream, 
	boolean leaveInnerStreamOpen
public function NegotiateStream (
	innerStream : Stream, 
	leaveInnerStreamOpen : boolean
Not applicable.



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


true to indicate that closing this NegotiateStream has no effect on innerstream; false to indicate that closing this NegotiateStream also closes innerStream. See the Remarks section for more information.

Exception typeCondition


innerStream is a null reference (Nothing in Visual Basic).

- or -

innerStream is equal to Null.

When you specify true for the leaveStreamOpen parameter, closing the NegotiateStream has no effect on the innerStream stream; you must explicitly close innerStream when you no longer need it.

The following code example demonstrates calling this constructor. This code example is part of a larger example provided for the NegotiateStream class.

// 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.
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);
