Example

This example gets and sets custom DICOM class information.

using Leadtools.Dicom.Common.DataTypes; 
using Leadtools.Dicom.Common.Extensions; 
using Leadtools.Dicom; 
using Leadtools.Dicom.Common.Editing.Converters; 
using Leadtools.Dicom.Common.Editing; 
 
 
 
public class MyPatientInfo 
{ 
   private PersonName _PatientName; 
 
   [Element(DicomTag.PatientName, Optional = true)] 
   [TypeConverter(typeof(PersonNameConverter))] 
   public PersonName PatientName 
   { 
      get { return _PatientName; } 
      set { _PatientName = value; } 
   } 
 
   private string _PatientID; 
   [Element(DicomTag.PatientID, Optional = false)] 
   public string PatientID 
   { 
      get { return _PatientID; } 
      set { _PatientID = value; } 
   } 
}
