determine geometry type

I'm creating a generic worflow against several layers in a map services.

How can I test for geometry type (point, line, polyon) for a layer in a map service?

Layer 1 Is it a point or Area or Line?

Depending on the geometrytype...different calculations will occur.

  Hi Ken,

  Reading map service info in JSON format might help. Use DownloadString to get JSON text and JsonToDictionary to retrieve geometry type info. Please see below.

  <FeatureSet>.GeometryType.ToString

  That way you can use an IF statement to test for a specific GeometryType. Point/Polyline/Polygon.
