CreateRow Method (AnnotationFeatureClass)
Creates a new annotation feature in the feature class with a system assigned object ID.
This method must be called on the MCT. Use QueuedTask.Run.
Creating a new Annotation Feature in an Annotation FeatureClass using a RowBuffer
public async Task CreatingAnAnnotationFeature(Geodatabase geodatabase)
{
await ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() =>
{
using (AnnotationFeatureClass annotationFeatureClass = geodatabase.OpenDataset<AnnotationFeatureClass>("Annotation // feature // class // name"))
using (AnnotationFeatureClassDefinition annotationFeatureClassDefinition = annotationFeatureClass.GetDefinition())
using (RowBuffer rowBuffer = annotationFeatureClass.CreateRowBuffer())
using (AnnotationFeature annotationFeature = annotationFeatureClass.CreateRow(rowBuffer))
{
annotationFeature.SetAnnotationClassID(0);
annotationFeature.SetStatus(AnnotationStatus.Placed);
// Get the annotation labels from the label collection
IReadOnlyList<CIMLabelClass> labelClasses =
annotationFeatureClassDefinition.GetLabelClassCollection();
// Setup the symbol reference with the symbol id and the text symbol
CIMSymbolReference cimSymbolReference = new CIMSymbolReference();
cimSymbolReference.Symbol = labelClasses[0].TextSymbol.Symbol;
cimSymbolReference.SymbolName = labelClasses[0].TextSymbol.SymbolName;
// Setup the text graphic
CIMTextGraphic cimTextGraphic = new CIMTextGraphic();
cimTextGraphic.Text = "Charlotte, North Carolina";
cimTextGraphic.Shape = new MapPointBuilderEx(new Coordinate2D(-80.843, 35.234), SpatialReferences.WGS84).ToGeometry();
cimTextGraphic.Symbol = cimSymbolReference;
// Set the symbol reference on the graphic and store
annotationFeature.SetGraphic(cimTextGraphic);
annotationFeature.Store();
}
});
