Example

using Leadtools; 
using Leadtools.Dicom; 
 
 
public void TestVRTable() 
{ 
 
   //Make sure to initialize the DICOM engine, this needs to be done only once  
   //In the whole application 
   DicomEngine.Startup(); 
 
   //We don't need to call this since the DicomEngine.Startup already does that for us 
   //These calls are for demonstration purposes only 
   DicomVRTable.Instance.Reset(); 
   DicomVRTable.Instance.Default(); 
 
   //We can also call FindByIndex if we know the index of this VR 
   DicomVR vr = DicomVRTable.Instance.Find(DicomVRType.AE); 
   DicomVRTable.Instance.Delete(vr); 
 
   DicomVR vr1 = DicomVRTable.Instance.Insert(DicomVRType.AE, "My AE VR", 16, DicomVRRestriction.StringFixed, 1); 
   Debug.Assert(DicomVRTable.Instance.Exists(vr1) == true); 
   DicomVRTable.Instance.SetName(vr1, "My New AE VR"); 
 
   int count = 0; 
   //If we want to loop through all the VRs in the table we can do this: 
   vr = DicomVRTable.Instance.GetFirst(); 
   while (vr != null) 
   { 
      // We can also access the rest of the properties of DicomVR in here, 
      // such as DicomVRType.Code, DicomVRType.Length, DicomVRType.Name, 
      // DicomVRType.Restriction and DicomVRType.UnitSize 
      if (vr.Code == DicomVRType.AE) 
      { 
         Console.WriteLine(vr.Name); 
      } 
      count++; 
      vr = DicomVRTable.Instance.GetNext(vr); 
   } 
   //We can use GetLast and GetPrevious to achieve the same thing 
 
   Debug.Assert(count == DicomVRTable.Instance.GetCount()); 
 
   DicomEngine.Shutdown(); 
}
