    In This Topic
    Represents the spatial component of a filter used when querying a FeatureClass.

    Example
    Use Select or Search with a Spatial Query
    //var featSceneLayer = ...;
    //var sname = featSceneLayer.Name;
    await QueuedTask.Run(() =>
    {
      if (!featSceneLayer.HasAssociatedFeatureService)
        return;//no search or select
    
      //Select all features within the current map view
      var sz = MapView.Active.GetViewSize();
      var map_pt1 = MapView.Active.ClientToMap(new System.Windows.Point(0, sz.Height));
      var map_pt2 = MapView.Active.ClientToMap(new System.Windows.Point(sz.Width, 0));
    
      //Convert to an envelope
      var temp_env = EnvelopeBuilderEx.CreateEnvelope(map_pt1, map_pt2, MapView.Active.Map.SpatialReference);
    
      //Project if needed to the layer spatial ref
      SpatialReference sr = null;
      using (var fc = featSceneLayer.GetFeatureClass())
      using (var fdef = fc.GetDefinition())
        sr = fdef.GetSpatialReference();
    
      var env = GeometryEngine.Instance.Project(temp_env, sr) as Envelope;
    
      //Set up a query filter
      var sf = new SpatialQueryFilter()
      {
        FilterGeometry = env,
        SpatialRelationship = SpatialRelationship.Intersects,
        SubFields = "*"
      };
    
      //Select against the feature service
      var select = featSceneLayer.Select(sf);
      if (select.GetCount() > 0)
      {
        //enumerate over the selected features
        using (var rc = select.Search())
        {
          while (rc.MoveNext())
          {
            using (var feature = rc.Current as Feature)
            {
              var oid = feature.GetObjectID();
              //etc.
            }
          }
