public: 
DicomVR^ Find(  
   DicomVRType code 
)

Parameters

code
A value representation code. DicomVR class in the Value Representation Table that has this value representation code will be returned.

Return Value

DicomVR that contains the item with the specified value representation code.

Remarks

As an example, if you call this method with code set to DicomVRType.AE, and the Value Representation Table filled with the default values, the returned DicomVR class will contain DicomVRType.AE, "Application Entity", 16, DicomVRRestriction.StringMaximum, and 1.
To see the default values for the Value Representation Table, refer to the Default Value Representation Table.

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(); 
}
