Class FeatureCollectionTable
A feature collection table represents an individual feature table in a FeatureCollection.
Implements
Namespace: Esri.ArcGISRuntime.Data
Assembly: Esri.ArcGISRuntime.dll
Syntax
public class FeatureCollectionTable : FeatureTable, INotifyPropertyChanged, ILoadable, IFeatureSet, IEnumerable<Feature>, IEnumerableRemarks
A FeatureCollectionTable consists of a feature definition (table schema) and a set of features that match that feature definition. You can obtain a FeatureCollectionTable from an existing Tables collection or you can create a new FeatureCollectionTable programmatically in your app.
To create a new FeatureCollectionTable, you can use a constructor that defines a set of fields, the geometry type, and spatial reference, and then populate it by adding new features. Alternatively, you can create a new FeatureCollectionTable from an IFeatureSet, such as the FeatureQueryResult returned from QueryFeaturesAsync(QueryParameters).
To render the features in a map or scene, add the FeatureCollectionTable to a Tables collection, construct a FeatureCollectionLayer from the FeatureCollection, and add it to the map or scene's collection of operational layers. To specify the FeatureCollectionTable symbology, apply a renderer to the Renderer property. If required, you can override this symbology on a per-feature basis using the SetSymbolOverride(Feature, Symbol).
