Retrieve spline information

Hi,

I've created a spline using API "ICreateSplineByEqnParams()" of sketch manager which gives ISketchSegment** as an output.

Now I convert that sketch segment into ISketchSpline** by using "QueryInterface()".

Please tell me, how to retrieve the spline information like KnotArrayCount, ControlPointArrayCount etc.?

Thanks & regards,
