Example

This example compares two datasets with different patient IDs.

using Leadtools.Dicom.Common.Anonymization; 
using Leadtools.Dicom; 
using Leadtools.Dicom.Common.Compare; 
 
public void CompareSample() 
{ 
   string dicomFileNameIn = Path.Combine(LEAD_VARS.ImagesDir, "IMAGE3.dcm"); 
 
   using (DicomDataSet dataset1 = new DicomDataSet()) 
   { 
      dataset1.Load(dicomFileNameIn, DicomDataSetLoadFlags.None); 
      using (DicomDataSet dataset2 = new DicomDataSet()) 
      { 
         List<Difference> differences = null; 
 
         dataset2.Copy(dataset2, null, null); 
         // 
         // Set a different value for patient id 
         // 
 
         dataset2.InsertElementAndSetValue(DicomTag.PatientID, "DifferentValue"); 
         differences = dataset1.Compare(dataset2); 
         foreach (Difference difference in differences) 
         {
