可以不用ITopologicalOperator，直接用空间查询就可以实现
//spatial uery
ISpatialFilter pSpatialFilter = new SpatialFilterClass();
pSpatialFilter.Geometry = (IGeometry)pPolyline;//用于查询的polyline
SpatialFilter.SpatialRel = esriSpatialRelEnum.esriSpatialRelIntersects;//Intersect
IFeatureCursor pFeatureCursor = pFeatureClass.Search(pSpatialFilter, false);//uery
IFeature pFeature = pFeatureCursor.NextFeature();
while (pFeature != null)
{
IPolyline pueryPolyline = (IPolyline)pFeature.Shape ; //查询出来的polyline
pFeature = pFeatureCursor.NextFeature();
//release com resource
System.Runtime.InteropServices.Marshal.ReleaseComObject(pFeatureCursor);}
//spatial uery
ISpatialFilter pSpatialFilter = new SpatialFilterClass();
pSpatialFilter.Geometry = (IGeometry)pPolyline;//用于查询的polyline
SpatialFilter.SpatialRel = esriSpatialRelEnum.esriSpatialRelIntersects;//Intersect
IFeatureCursor pFeatureCursor = pFeatureClass.Search(pSpatialFilter, false);//uery
IFeature pFeature = pFeatureCursor.NextFeature();
while (pFeature != null)
{
IPolyline pueryPolyline = (IPolyline)pFeature.Shape ; //查询出来的polyline
pFeature = pFeatureCursor.NextFeature();
//release com resource
System.Runtime.InteropServices.Marshal.ReleaseComObject(pFeatureCursor);}
