you mean the intersection, right? see here: ArcObjects Help for .NET developers (ITopologicalOperator.Intersect)

thanks for your reply，actually，it is not the intersection

i mean，some parts of two line，in the spatial，are almost same

i need get the same part

do you see the graphic in the link to the documentation for ITopologicalOperator.Intersect?

I guess the example with the two lines shows the solution for your problem... or i don't get it

thanks，you are right，i did not think about it carefully

thanks a lot
