Question

Hi all
I want to cut a polygon by many polylines but i don't know how to do it.
I can cut polygon to 2 parts ( left and right ) using this code
ESRI.ArcGIS.Geometry.ITopologicalOperator4 topologicalOperator4 = polygon as ESRI.ArcGIS.Geometry.ITopologicalOperator4; 
ESRI.ArcGIS.Geometry.IGeometryCollection geometryCollection = topologicalOperator4.Cut2(polyline);

But how to cut by many polylines.
Waitting  for your help.
