Description

Gets the ith Point from the PointCollection. The first Point in the PointCollection has index 0, and the last Point has index equal to PointCount - 1. (Alternatively, the last Point in the PointCollection can be referenced using index -1.).

Remarks

Note: Since a copy of the point is returned by Point (get_Point) for path, ring, polyline and polygon the IPointCollection::UpdatePoint method must be used to update points on those geometry types.
