NEventReport Method

In This Topic

Send an N-EVENT-REPORT over an established DicomAssociation

Syntax

Visual Basic
C#

'Declaration
 
Public Sub NEventReport( _
   ByVal SOPClassUID As System.String, _
   ByVal InstanceUID As System.String, _
   ByVal EventID As System.Integer, _
   ByVal DataSet As DicomDataSet _
)

public void NEventReport( 
   System.string SOPClassUID,
   System.string InstanceUID,
   System.int EventID,
   DicomDataSet DataSet
)

Parameters

SOPClassUID: The requested SOP Class UID
InstanceUID: The requested SOP InstanceUID
EventID: Event ID, as defined by the Class UID
DataSet: Associated Data

Remarks

Before using this method, it is important to ensure that the required SOP Class UID has been negotiated with the remote entity. In some cases such as when using Storage Commitment, reverse role SCU/SCP negotiation may also be necessary.

The return status can be found in the LastStatus property of DicomAssociation object.

Example

using (var cn = new DicomAssociation())
{
    DicomDataSet ds = new DicomDataSet(); 
    ds.Add(Keyword.PerformedProcedureStepStatus, "COMPLETED");
    ds.Add(Keyword.PerformedProcedureStepEndDate, "20250725");
    ds.Add(Keyword.PerformedProcedureStepEndTime, "154500");
    
    cn.RequestedContexts.Add(SOPClasses.ModalityPerformedProcedureStep);
    cn.Open("localhost", 104, "callingAET", "calledAET");
    
    string sopClassUID = SOPClasses.ModalityPerformedProcedureStep;
    string instanceUID = "1.2.840.113619.2.55.3.604688745.703";
    int eventID = 1; // 1 (Storage Commitment Request Successful)
    cn.NEventReport(sopClassUID, instanceUID, eventID, ds);
    
    // List containing result status codes returned
    var moveStatus = cn.Status;
    // Result of last status code 
    var status = cn.LastStatus;
    
    cn.Close();
}

Target Platforms: .NET CLR 4.8 or higher
