Getting sub layers from ArcGISDynamicMapservice

I have a rest service url which I have used to create dynamic service and added it to the map. I want to loop through the arcgis dynamic map service layer to access feature layers in it.Is there any way to access feature layers in arcgis dynamic layer ?

I think I have found a solution to my problem. I am using the following to get details of a feature layer from ArcGISDynamicServiceMapLayer and applying the required query definition to it.

ArcGISDynamicMapServiceLayer dynamicLayer=myMap.Layers["myDynamicLayer"] as ArcGISDynamicMapServiceLayer;

string query="";

dynamicLayer.GetDetails(layerID,(ESRI.ArcGIS.Client.FeatuerService.FeatureLayerInfo myFeatureLayer,Exception ex) => {

if(ex == null)

{

query=myFeatureLayer.DefinitionExpression;

System.Collections.ObjectModel.ObservableCollection<LayerDefination> definitionCollection = new System.Collections.ObjectModel.ObservableCollection<LayerDefination>();

LayerDefinition layerDef=new LayerDefinition();

layerDef.ID=layerID;

layerDef.Definition=query+" AND Count > 100";

definitionCollection.Add(layerDef);

dynamicLayer.LayerDefinitions=definitionCollection;

dynamicLayer.Refresh();

}
