How to get the coordinates of a selected feature?

JaewonYang

In my add-in project I have many layers (points, polylines, polygons). I want to get the coordinates of a feature selected from any feature layer in the list through a map tool and show into the text boxes of a winform. Until now I could only find a sample to return the coordinates of a point clicked on the map.

Hi Jaewon,

This is code combined from few ArcGIS Pro snippets:

 var firstLayer = MapView.Active.Map.GetLayersAsFlattenedList().OfType<FeatureLayer>().FirstOrDefault();
 var selectionfromMap = firstLayer.GetSelection();

        ArcGIS.Core.Data.QueryFilter filter = new ArcGIS.Core.Data.QueryFilter
        {
          ObjectIDs= selectionfromMap.GetObjectIDs();
        };

        // get the row
        using (ArcGIS.Core.Data.RowCursor rowCursor = featureClass.Search(filter, false))
        {
          while (rowCursor.MoveNext())
          {
            long oid = rowCursor.Current.GetObjectID();

            // get the shape from the row
            ArcGIS.Core.Data.Feature feature = rowCursor.Current as ArcGIS.Core.Data.Feature;
            Polygon polygon = feature.GetShape() as Polygon;

            // get the attribute from the row (assume it's a double field)
            double value = (double)rowCursor.Current.GetOriginalValue(fldIndex);

            // do something here
          }
        }
