Defines the base class for layers in the map.

Object Model

Syntax

Visual Basic (Declaration)
Public MustInherit Class Layer Implements ILayer

C#
public abstract class Layer : ILayer

Example

Assuming you have a MobileService called mobileService1, the following code example shows how to use mapLayer data to find position for raster layers in mapLayer collection.

C#	Copy Code
`// Generic List holding indexes of raster layers in the map List<int> RasterLayerIdx = new List<int>(); int iCnt = mobileService1.Layers.Count; for (int i = 0; i < iCnt; i++) { MobileServiceLayer layer = mobileService1.Layers[i]; if (layer.GetType() == typeof(RasterLayer)) RasterLayerIdx.Add(i); }`

The following example shows how to check the layer type in the MobileServiceLayerCollection.

C#	Copy Code
`string info = ""; foreach (MobileServiceLayer cl in mobileService1.Layers) { if (cl.GetType() == typeof(FeatureLayer)) info = info + "\n" + cl.Name + ": FeatureLayer"; if (cl.GetType() == typeof(RasterLayer)) info = info + "\n" + cl.Name + ": RasterLayer"; if (cl.GetType() == typeof(AnnotationLayer)) info = info + "\n" + cl.Name + ": AnnotationLayer"; } MessageBox.Show(info);`

Remarks

As Layer is an abstract class for many other classes such as MobileServiceLayer, MobileCacheLayer, FeatureLayer, and so on. it provides basic properties/methods/events that are accessible from other classes. For more information, see MobileServiceLayer and MapLayer.
