解决办法

Use C# code: public void OnClick() { try { IWorkspaceFactory wsFact = new FileGDBWorkspaceFactoryClass(); IFeatureWorkspace featWS = (IFeatureWorkspace)wsFact.OpenFromFile(@"<a href="file:C:/incidents/792309/Test.gdb" target="_blank">C:\incidents\792309\Test.gdb</a>", 0); IFeatureClass featClsPoly = featWS.OpenFeatureClass("Polygon"); IFeatureClass featClsLine = featWS.OpenFeatureClass("Polyline"); object obj = Type.Missing; IGeometryCollection geomCollGon = new GeometryBagClass() as IGeometryCollection; IFeatureCursor featCur = featClsPoly.Search(null, false); IFeature feat = featCur.NextFeature(); while (feat != null) { geomCollGon.AddGeometry(feat.ShapeCopy, ref obj, ref obj); feat = featCur.NextFeature(); } IGeometryCollection geomCollLine = new GeometryBagClass() as IGeometryCollection; featCur = featClsLine.Search(null, false); feat = featCur.NextFeature(); while (feat != null) { geomCollLine.AddGeometry(feat.ShapeCopy, ref obj, ref obj); feat = featCur.NextFeature(); } IRelationalOperatorNxM relOpNxM = geomCollGon as IRelationalOperatorNxM; IRelationResult relRes = relOpNxM.Crosses(geomCollLine as IGeometryBag); int count = relRes.RelationElementCount; int left, right; for (int i = 0; i < count; i++) { relRes.RelationElement(i, out left, out right); IGeometry geomGon = geomCollGon.get_Geometry(left); IGeometry geomLine = geomCollLine.get_Geometry(right); } } catch (Exception e) { MessageBox.Show(e.Message); } }
