Selection to Feature

DavidMrázek — Mon, 25 Apr 2022 07:59:59 GMT

Good day,
is there any way to make Selection a Feature? It may be primitive, but I'm not sure.

var gsSelection = lyrList.GetSelection(); var polyFeature2 = gsSelection as Feature;//here is the error: Cannot convert type 'ArcGIS.Core.Data.Selection' to 'ArcGIS.Core.Data.Feature' via a reference conversion, boxing conversion, unboxing conversion, wrapping conversion, or null type conversion var polygonGeometry2 = polyFeature2.GetShape() as Polygon; var mapPoint1 = GeometryEngine.Instance.Centroid(polygonGeometry2);

Thank you

David

Hi,

You need to get cursor from selection:

using (var rowCursor = gsSelection.Search(null)) { while (rowCursor.MoveNext()) { using (var polyFeature2 = rowCursor.Current as Feature) { // Your code here } } }

And is it possible to use while-LOOP for only one pass?

I don't know what you exactly mean "use while-LOOP for only one pass". If you want to get only one feature, you can change "while" to "if". If you want to go through selection few times, so you need each time make new search. Cursor works one time only
