HOW TO GET FEATURECLASS FROM LAYER

To get feature class (IFeatureClass) from ILayer, we first need to get the IFeatureLayer from ILayer and then IFeatureClass from IFeatureLayer.

Example:

private IFeatureClass getFeatureClass(ILayer pLayer)
{
    IFeatureLayer featLyr = lyr as FeatureLayer;
    IFeatureClass featCls = featLyr.FeatureClass;
    return featCls;
}
