Open(Socket,Stream,String,String) Method

In This Topic

Open a DICOM association over an independently created System.Net.Sockets.NetworkStream

Syntax

Visual Basic
C#

'Declaration
 
Public Overloads Sub Open( _
   ByVal Socket As System.Net.Sockets.Socket, _
   ByVal Stream As System.IO.Stream, _
   ByVal CallingAE As System.String, _
   ByVal CalledAE As System.String _
)

public void Open( 
   System.Net.Sockets.Socket Socket,
   System.IO.Stream Stream,
   System.string CallingAE,
   System.string CalledAE
)

Parameters

Socket: Specifies the underlying Socket through which an association should be made.
Stream: The NetworkStream via which the connection is to be made
CallingAE: Name to quote for this Application Entity
CalledAE: Name of remote Application Entity

Remarks

This version is useful in some security scenarios, as the NetworkStream may be negotiated and verified before starting DICOM negoations. Note that both the NetworkStream and underlying Socket need to be specified, as some controls (such as timeout values) are only valid when applied to the socket. This method returns, after the connection has been established. If there is a protocol failure, then a trappable DicomException is thrown.

Example

DicomImage image = new DicomImage("image.dcm");
                    
string node = "dicomserver.co.uk";     
int port = 104;
string callingAE = "SCU";
string calledAE = "SCP";
 
Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
                    
IPAddress ip = Dns.GetHostEntry(node).AddressList.First(addr => addr.AddressFamily == AddressFamily.InterNetwork);
socket.Connect(new IPEndPoint(ip, port));
                    
NetworkStream stream = new NetworkStream(socket);
                    
using (DicomAssociation cn = new DicomAssociation())
{
    cn.RequestedContexts.Add(image.SOPClass, TransferSyntaxes.ExplicitVRLittleEndian);
    cn.Open(socket, stream, callingAE, calledAE);
    cn.SendInstances(image);
    
    var result = cn.LastStatus;
    
    cn.Close();
}
