示例1: AddRegion
/// <summary>
/// This uses extent checking (rather than full polygon intersection checking). It will add
/// any members that are either contained by or intersect with the specified region
/// depending on the SelectionMode property. The order of operation is the region
/// acting on the feature, so Contains, for instance, would work with points.
/// </summary>
/// <param name="region"></param>
/// <param name="affectedArea">The affected area of this addition</param>
/// <returns>True if any item was actually added to the collection</returns>
