在mapx中，怎么得到一条折线段是几条线组成？

你可以看MAPX的Polyline features的相关帮助！
下面这个事例，你可以借鉴
Examining the Nodes that Make Up a Feature

This Visual Basic example demonstrates how the Parts collection and Points collection allow you to loop through all the points in a selected feature.

Dim obj as MapXLib.Feature  

Dim pts as new Points

Dim pt as new Point

set obj = map1.layers(1).selection(1)

for each pts in obj.parts

  for each pt in pts

    debug.print pt.x, pt.y

  next
