    SelectionCombinationMethod Enumeration
    In This Topic
    Define combination methods for selection operations. They determine how the selection performed will combine with an existing selection.
    Add Adds to the current selection.
    And Selects from the current selection.
    New Creates a new selection.
    Subtract Subtracts from the current selection.
    XOR Performs an 'exclusive or' with the current selection.
    Spatial selection of elements in all Graphics Layers
    //Map Tool is used to perform Spatial selection.
    //Graphic selection uses the selection geometry 
    //to intersect the geometries of those elements (graphic or group) 
    //that will be selected and then highlights them. 
    protected override async Task<bool> OnSketchCompleteAsync(Geometry geometry)
      var selPoly = geometry as Polygon;
      return await QueuedTask.Run(() =>
        //note: the selected elements may belong to more than one layer...
        var elems = MapView.Active.SelectElements(selPoly, SelectionCombinationMethod.New);
        return true;
    Spatial selection of elements in one graphics layer
    //on the QueuedTask
    //Create an extent to use for the spatial selection
    var extent = MapView.Active.Extent;
    var selectionExtent = extent.Expand(0.5, 0.5, true);
    //Select elements in specified graphics layer using the selection extent.
    var selectedElements = MapView.Active.SelectElements(graphicsLayer, selectionExtent, SelectionCombinationMethod.Add);
    Select Text Graphic Elements
    var graphicsLayer = MapView.Active.Map.GetLayersAsFlattenedList()
    if (graphicsLayer == null)
    var all_text = graphicsLayer.GetElementsAsFlattenedList()
                  .Where(e => e.GetGraphic() is CIMTextGraphic);
