Get points along a polyline at defined distance

Hello,

i need to store into my array the points along the polyline each defined distance.
Example:
The Polyline lenght is 50m, i set interval to 5m. I have to store in the array all the points along the polyline each 5meter.(points on 0m-5m-10m-15m....).

I'm using c#.
Any function to get theese points?

Thanks,
Andrea
