Select Points Outside of a Polygon

Question

Hello,

I have a PointCollection and a Polygon. I want to select all of the points from the PointCollection that are not inside the Polygon. I thought that I could use GeometryEngine.Difference but it seems that a PointCollection is not valid for a parameter.

Does anyone have an idea on how best to do this?

Thanks

I'm not hugely familiar with .NET any more, but could you not create a MultiPoint from the PointCollection (looks like PointCollection implements the right interface to fit the MultiPoint constructor) and then pass that multipoint into GeometryEngine.Difference() along with the polygon?
