Straight line passing through the viewable area

Hello,

[WPF version]

Is there a way to determine that a straight line passes through the viewable area of the map. I have 2 points (extremities of the line) and when we're zoomed in very close, both ends of the line might fall outside of the 'zoomed in' viewable area but the line still goes through the viewable area. I tried the the BoundsOfMap, but with no luck.

Thanks,
