I have a problem when inserting features with polygon feature class in FGDB. This is my code:
... initialising some fields (does not affect performance) m_featureBuffer.Shape = CreateShape(feature); m_insertCursor.InsertFeature(m_featureBuffer);CreateShape:
protected override ESRI.ArcGIS.Geometry.IGeometry CreateShape(IAbstractFeature feature) { IArea area = (IArea)feature; ESRI.ArcGIS.Geometry.IPointCollection polygon = new ESRI.ArcGIS.Geometry.PolygonClass(); foreach (Point2D point2d in area.Polygon.OuterBoundaryIs.Coordinates) { ESRI.ArcGIS.Geometry.IPoint point = new ESRI.ArcGIS.Geometry.PointClass(); point.PutCoords(point2d.X, point2d.Y); polygon.AddPoint(point); } return (ESRI.ArcGIS.Geometry.IGeometry)polygon; }In this case inserting ~1500 polygons takes about ~110 seconds. If I comment this line
m_featureBuffer.Shape = CreateShape(feature);the insert takes ~10 seconds! If I create empty polygons and pass them in the Shape property of the feature buffer, it takes ~10 seconds too.
I tried to use the IFeatureClassLoad according to the ESRI example, but it doesn't help with the performance.
