C#: Referencing elevation data with a Street-Route

[SebastianKrings]

Hello,

as I'm looking for a solution in this thread: http://forums.arcgis.com/threads/32069-Streetmap-with-elevation-Data

I thought if this may is only/also possible programmatically (in C#) to solve.
I have elevation data (source was a raster, now I converted it to point-features) and a street-layer.
Then I want to create a route and want to read out which elevations are on my route.
I think the data has also be interpolated because not all street-points are hit by the elevation data.

Thanks for any help and ideas.
