ShapeType constant values for Polygons

DorisRiedl — Tue, 05 Jun 2012 10:36:01 GMT

I tried to query if a FeatureClass is of type polygon:

[INDENT][/INDENT]if (pFC.getShapeType() == esriShapeType.esriShapePolygon || pFC.getShapeType() == esriShapeType.esriShapePolygonZ) { ... }

but this doesn't seem to work. Is it possible that there is an error in the esriShapeType constants (which should be 5 for polygons and 19 for polygonZ)? Because when I show them via a MessageDialog
[INDENT][/INDENT]JOptionPane.shwoMessageDialog(null, pFC.getShapeType());
the output for Polygons is always 4.

The esriShapeType constants for point and polyline work all right.

Any hints?

The ShapeType property doesn't return an esriShapeType constant, but rather an esriGeometryType constant. Your code should be

if (pFC.getShapeType() == esriGeometryType.esriGeometryPolygon)

but there is no constant for a PolygonZ

Thanks Ken!
