Featurelayer to Geometry

jamesborris — Thu, 01 Mar 2012 18:56:57 GMT

In c# .net how to I get the geometry of a feature layer using arcobjects? Its probably simple but i'm new to this. I tried to cast to it but i didn't work.
below is a quick sample.

IFeatureClass pEventFC;
pName = (IName) pRESN;

pEventFC = (IFeatureClass) pName.Open();

IActiveView pActive;
pFLayer = new FeatureLayerClass();
pFLayer.FeatureClass = pEventFC;

IGeometry pGeom;

pGeom = (IGeometry)pFlayer

Any clues?

A feature layer doesn't have a geometry. A feature layer contains features, each of which have a geometry. You can get the features from a feature layer via a query. The query can be an attribute query or a spatial query. Here is one example.

Dim featureCursor As IFeatureCursor = featureLayer.FeatureClass.Search(Nothing, False) Dim feature As IFeature = featureCursor.NextFeature Do While feature IsNot Nothing     Dim geometry As IGeometry = feature.ShapeCopy     feature = featureCursor.NextFeature Loop
