points in a polyline from multiple lines that cross

How to obtain the points in a polyline from multiple lines that cross the polyline.

I have a polyline that is crossed by several lines and would like to get the points of intersection of the same to fetch the distances from the start of the polyline.

You can do:

For each line that intersects with the polyline, you can find the intersection point with Line.IntersectWith() method. Then, with Polyline.GetDistanceAtPoint() to find out the distance fron the polyline's start point to the intersection point (along the ployline).
