I'm deleting a feature from a shapefile with this code:

IWorkspaceFactory workspaceFactory = new ShapefileWorkspaceFactory();
IFeatureWorkspace featureWorkspace = (IFeatureWorkspace)workspaceFactory.openFromFile("C:/Users/me/Desktop", 0);
IFeatureClass featureClass = featureWorkspace.openFeatureClass("sondage");
IWorkspaceEdit wse=(IWorkspaceEdit)featureWorkspace;
IQueryFilter qf=new QueryFilter();
String s="SALB 01";
IFeatureCursor pFeatureCursor = featureClass.search(qf, false);                 
int id=pFeatureCursor.nextFeature().getOID();
IFeature feat=featureClass.getFeature(id);

It works, but when I called this function in another class in the same project, the feature is not deleted and the shape couldn't be drawn any more.


Please use an update cursor and not a search cursor. You can replace the table/row by featureclass/feature from my example.

ICursor cur = table.Update(queryFilter, false);
if (cur != null)
    IRow row = cur.NextRow();
    if (row != null)
        while (row != null)
            row = cur.NextRow();

Note: Please keep in mind to handle when no features or multiple features are returned in the cursor.

  • Thank you very much, that works, i think the problem is that i wasn't using the releaseComObject. – Mouad Sep 12 '16 at 14:39
  • Why did you "ReleaseComObject"? – Chris Stayte Nov 9 '16 at 18:16
  • since you are using "while" loop "if (row != null)" is not necessary. Thanks for tje solution, though :) – shika-kun Feb 27 '19 at 15:28
