Example

Many examples in the Library Reference reference the LayerCollection of the map, including Remove and FeatureLayer.CreateSelectionLayer(Point, double, Renderer, string).

Remarks

Each MapView has a Layers property which references a LayerCollection. This collection can be managed with the methods in this class. Layers may be added (Add, AddRange(Layer[]), AddRange(LayerCollection), Insert), deleted (Remove, RemoveAt), and moved within the collection (MoveTo). Besides iterating through the collection to retrieve layers (this Property), you can also locate layers by name (FindByName(string), FindByName(string, int)).

A DataFrame also has a Layers property with a LayerCollection. That collection may not be modified. Only the visibility of layers within the collection may be changed.

The layer collection is a 0-based collection. Lower-numbered layers draw first, with the last layer in the collection drawing at the top of the map.
