Remarks

Maps are typically composed of numerous layers from various data sources.  Use the Layer property to access a particular layer in a map.  The collection of layers is 0-based.  Use the Layer property in conjunction with the LayerCount property to loop through all the layers in the map.

The Layer property returns an ILayer reference; attempt a Query Interface to determine the type of layer object.  For example, do not assume that all layers in a map are FeatureLayers. Valid layers are those that implement ILayer and IDataLayer.

Each Map also has a basic graphics layer (CompositeGraphicLayer) that is not comprised in the collection of layers returned by this property; a reference to this layer is obtainable through the BasicGraphicsLayer property.
