Get floor location

[Anonymous]

I'm trying to get the location point of a floor, so I found this code on a other topic : 

                        LocationCurve lc = floor.Location as LocationCurve;
                        Line l = lc.Curve as Line;
                        XYZ locPts = l.GetEndPoint(0) as XYZ;

But i get a NullReferenceExcepetion on the second line and I Don't know how to solve it.

If someone has an idea.

Floor doesn't have a location object.

You can get the centroid from the solid of the geometry, max/min of bounding box or you can analyse the sketch boundary to determine the point you consider to be the floors location.
