Extract Spatial ID from a Polygon

Question

Hi,

I am new to ArcObjects, I am spinning my wheels extracting Spatial ID from a polygon. I have a features with 100 blocks when I add a point features on polygon feature. I need its ID.

Any help or link is appreciated.

You need to spend more time constructing your question so it will be understood.  It appears you are trying to to search polygons with a point feature.  If this is so you want to start by creating a spatial filter

Here is a sample that is set up to intersect:

public static ISpatialFilter CreateSpatialFilter(IFeatureClass fc, IGeometry shape)
        {
            if (fc == null) return null;
            ISpatialFilter sf = new SpatialFilterClass();
            sf.GeometryField = fc.ShapeFieldName;
            sf.Geometry = shape; 
            sf.SpatialRel = esriSpatialRelEnum.esriSpatialRelIntersects;
            return sf;
        }

Then you can use this directly on your feature class using the Search function..

IFeatureCursor fcursor = fc.Search(CreateSpatialFilter(fc, shape), true);

Now index through the cursor to get the polygon id's.

Good Luck
