How to split polyline at vertices?

Question

Hi,

How can I split polyline at its vertices?

There is SplitLine tools in geoprocessing, but generate geoprocessing object and execute it is slow.

Is there any other way to split?

Thanks.

If you want to split your polyline at any vertex, maybe you should to use ISegmentCollection objSegmentCol = igConvexHullLine as ISegmentCollection;
do you mean to this result?
Yes. I tried, but failed.

Here's my code for that.

IPolyline plConvexHullLine = (IPolyline)igConvexHullLine;
                for (int e = 0; e < pcVertices.PointCount; e++)
                {
                    IPoint ptIn = pcVertices.get_Point(e);
                    int f;
                    int g;
                    Boolean k;
                    plConvexHullLine.SplitAtPoint(ptIn, false, true, out k, out f, out g);
                }

is there any problem with my code?
