    Transformations Property (CompositeHVDatumTransformation)
    In This Topic
    Gets the list of transformations in this composite transformation.
    Syntax
    public IList<HVDatumTransformation> Transformations {get;}
    Public ReadOnly Property Transformations As IList(Of HVDatumTransformation)
    Example
    Create Composite HV Datum Transformation
    HVDatumTransformation hv1 = HVDatumTransformation.Create(108034);
    HVDatumTransformation hv2 = HVDatumTransformation.Create(108033, false);
    List<HVDatumTransformation> hvs = new List<HVDatumTransformation>() { hv1, hv2 };
    
    // create from enumeration
    CompositeHVDatumTransformation compositehv = 
                    CompositeHVDatumTransformation.Create(hvs);
    int count = compositehv.Count;      // count = 2
    
    List<HVDatumTransformation> transforms = 
                   compositehv.Transformations as List<HVDatumTransformation>;
    HVDatumTransformation tranform = transforms[0];
    // transform.Wkid = 108034
    
    // get inverse
    CompositeHVDatumTransformation inverse_compositehv = 
           compositehv.GetInverse() as CompositeHVDatumTransformation;
    
    // create from xml
    string xml = compositehv.ToXml();
    //At 2.x - CompositeHVDatumTransformation xml_compositehv =
    //      CompositeHVDatumTransformation.CreateFromXML(xml);
    
    var xml_compositehv = CompositeHVDatumTransformation.CreateFromXml(xml);
    
    // create from json
    string json = compositehv.ToJson();
    CompositeHVDatumTransformation json_compositehv = 
        DatumTransformation.CreateFromJson(json) as CompositeHVDatumTransformation;
