Hello everyone,
as you can see from the attached example I set the node input as a Polyline:
but after building the project with the ScriptEditor (available for Rhino 8) the node gives me an exception:
Do I miss something?

A polyline is more or less a collection of points.
While a PolylineCurve derives from Curve,
you can ToPolyline() to get the underlying polyline from a polylineCurve
please post the code that causes the error.
Curve inputCrv;
Polyline polyline;
//
if (inputCrv is PolylineCurve pCrv)
{
polyline = pCrv.ToPolyline;
}
else
{
// error handling
}
//
// alternative
if (inputCrv.TrygetPolyline(out polyline))
{
//...
}
// or if you prefere
if (! inputCrv.TrygetPolyline(out polyline))
{
// error
return;
}
// ... go on with your logic here
Thank you I finally understand.
I set the input as Curve (not as Polyline):
private void RunScript(Curve inputCrv, ref object a)
{
Polyline polyLine = new Polyline();
if (inputCrv is PolylineCurve pCrv)
{
polyLine = pCrv.ToPolyline();
}
int npts = polyLine.Count;
a = npts;
}

without testing - do something like this.
and test it with a non - polyline curve.
private void RunScript(Curve inputCrv, ref object a)
{
// defaults and error
a = null;
Polyline polyLine = null;
if (inputCrv is PolylineCurve pCrv)
{
// success on polyline input
polyLine = pCrv.ToPolyline();
int npts = polyLine.Count;
a = npts;
}
}
