Here is a solution

angle must be close to Math.PI (3.14159)  for your purpose Math.Pi - angle tolerance  (1° in radian)

private void RunScript(Polyline c, double angle, ref object A, ref object B)
{

//Breaks polyline at kinks
Polyline[] crs = c.BreakAtAngles(angle);

//Take all the first points of polyline

List<Point3d> pts = new List<Point3d> ();
foreach (Polyline pl in crs)
{
     pts.Add(pl.First);
}

//Add the last point
pts.Add(crs[crs.Count() - 1].Last);

//Create the new polyline
A = new Polyline(pts);

}

try Polyline.ReduceSegments(tolerance);

Thanks Andrew,

before answering I read RhinoCommon help and I though this command will merge points close from each other. I didn't test it ! Bad idea. It is answering exactely the question of Platut.
