    TextSymbol Property (CIMLabelClass)
    In This Topic
    Gets or sets the text symbol of the label class.
    Syntax
    public CIMSymbolReference TextSymbol {get; set;}
    Public Property TextSymbol As CIMSymbolReference
    Example
    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();
        }
      });
    }
    Apply text symbol to a feature layer
    //Note: call within QueuedTask.Run()
    
    //Get the layer's definition
    var lyrDefn = featureLayer.GetDefinition() as CIMFeatureLayer;
    //Get the label classes - we need the first one
    var listLabelClasses = lyrDefn.LabelClasses.ToList();
    var theLabelClass = listLabelClasses.FirstOrDefault();
    //Set the label classes' symbol to the custom text symbol
    //Refer to the ProSnippets-TextSymbols wiki page for help with creating custom text symbols.
    //Example: var textSymbol = await CreateTextSymbolWithHaloAsync();
    theLabelClass.TextSymbol.Symbol = textSymbol;
    lyrDefn.LabelClasses = listLabelClasses.ToArray(); //Set the labelClasses back
    featureLayer.SetDefinition(lyrDefn); //set the layer's definition
                                         //set the label's visiblity
    featureLayer.SetLabelVisibility(true);
