Using IfeatureCursor to location a feature

IbrahimHussein — Sat, 11 Dec 2021 14:28:19 GMT

I have a IfeatureCursor that I initialized to null. When I try to set it with a IfeatsureSelection.SelectionSet.Search(,,out IfetureCursor) I get an error saying

cannot convert 'out ESRI.ArcGIS.Geodatabase.IFeatureCursor' to 'out ESRI.ArcGIS.Geodatabase.ICursor'

Code

            void SelectionChangedFunc()
            {
                IFeatureSelection featSel = default(IFeatureSelection); //link to a feature selection
                IFeatureCursor selCur = null;                           //feature cursor to iterate
                IFeature f = default(IFeature);                         //link to a feature


                featSel = p_addressLayer as IFeatureSelection;
                MessageBox.Show("changed"); //debugging purposes


                if (featSel.SelectionSet.Count > 0)
                {
                  
                    featSel.SelectionSet.Search(null, false, out selCur);
                    f = selCur.NextRow();
                    MessageBox.Show(f.Fields.FindField("STR_NAME").ToString()); //debugging purposes
                    MessageBox.Show(selCur.Fields.FindField("STR_NAME").ToString()); //debugging purposes
    
                }
            }

Line 15 is where the issue is. I tried casting with no luck. Anyone come accross this issue or was able to successfully use a IfeatureCursor in C# SDK 10.4

I've just tried using a IFeatureCursor in a search on a selection set using VBA in 10.4 and it worked for...

If your code is not actually accessing the geometry field, which it appears to be the case, why not try ICursor instead?

Hi duncan, I actually figured it out. I had to use ICursor like you suggested, and then cast it as a IFeatureCursor after I call the SelectionSet.Search function.
