示例1: GetFeaturesWithinGeometryAsync
private async Task<List<long>> GetFeaturesWithinGeometryAsync(FeatureLayer featureLayer)
{
return await QueuedTask.Run(() =>
{
List<long> oids = new List<long>();
//Get the client point edges
Point topLeft = new Point(_toolClickedPoint.X - PixelTolerance, _toolClickedPoint.Y + PixelTolerance);
Point bottomRight = new Point(_toolClickedPoint.X + PixelTolerance, _toolClickedPoint.Y - PixelTolerance);
//convert the client points to Map points
MapPoint mapTopLeft = MapView.Active.ClientToMap(topLeft);
MapPoint mapBottomRight = MapView.Active.ClientToMap(bottomRight);
//create a geometry using these points
Geometry envelopeGeometry = EnvelopeBuilder.CreateEnvelope(mapTopLeft, mapBottomRight);
if (envelopeGeometry == null)
return null;
//Spatial query to gather the OIDs of the features within the geometry
SpatialQueryFilter spatialQueryFilter = new SpatialQueryFilter
{
FilterGeometry = envelopeGeometry,
SpatialRelationship = SpatialRelationship.Intersects,
};
using (RowCursor rowCursor = featureLayer.Search(spatialQueryFilter))

using (Row row = rowCursor.Current)
{
var id = row.GetObjectID();
