C# - Reduce / Simplify Polyline Vertices

[cadVDJ3M]

Hello.

I would like to reduce the unnecessary vertices of a Polyline. Like the vertices that are highlighted in red in the image below.

Does anyone have an efficient solution?

I think of going through all the vertices checking the angle, and when it matches I could remove a vertex. But I think it would have problems in case of arcs.

Thank you.
