Source

0 - DICOM UL service-user (initiated abort)

1 - Reserved

2 - DICOM UL service-provider (initiated abort)

Reason

0 - reason-not-specified

1 - unrecognized-PDU

2 - unexpected-PDU

3 - reserved

4 - unrecognized-PDU parameter

5 - unexpected-PDU parameter

6 - invalid-PDU-parameter value

Example

using DicomObjects;
using DicomObjects.DicomUIDs;
            	    
   using (var cn = new DicomAssociation()) 
   {    
       byte reason = 0; // reason-not-specified
       byte source = 0; // DICOM UL service-user (initiated abort)
       
       cn.RequestedContexts.Add(SOPClasses.Verification);
       cn.Open("localhost", 104, "callingAET", "calledAET");        
       cn.Echo();
       
       // cn.Close() is unnecessary here; Abort already closes the association
       cn.Abort(reason, source);
   }
