C#

using (var cn = new DicomAssociation())    
{
    DicomDataSet ds = new DicomDataSet();
    ds.Add(Keyword.PerformedProcedureStepStatus, "COMPLETED");
    ds.Add(Keyword.PerformedProcedureStepEndDate, "20250725");
    ds.Add(Keyword.PerformedProcedureStepEndTime, "154500");
     
    var performedSeries = new DicomDataSet();
    performedSeries.Add(Keyword.SeriesInstanceUID, "1.2.840.1234.5678.91011.1");
    performedSeries.Add(Keyword.RetrieveAETitle, "STORESCP");
    performedSeries.Add(Keyword.ReferencedImageSequence, new DicomDataSetCollection());
     
    var seriesSeq = new DicomDataSetCollection();
    seriesSeq.Add(performedSeries);
    ds.Add(Keyword.PerformedSeriesSequence, seriesSeq);
     
    ds.Add(Keyword.PerformedProtocolCodeSequence, new DicomDataSetCollection());
    ds.Add(Keyword.ProcedureCodeSequence, new DicomDataSetCollection());
    ds.Add(Keyword.CommentsOnThePerformedProcedureStep, "Exam completed successfully.");
     
    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";
    
    cn.NSet(sopClassUID, instanceUID, ds);
    
    // List containing result status codes returned
    var moveStatus = cn.Status;
    // Result of last status code 
    var status = cn.LastStatus;
