PathData class unable to be serialized [RESOLVED]

[nemaroller]

So, I can't serialize PathData... why? I don't know... the best description I can get of PathData is that it is an array of bytes that encapsulates the points and point types in a graphics path. Seems to me an array of bytes should be serializable.

the PathData class encompasses an array of PointF structures (serializable), and PointType (serializable), so why can't the class be serialized?

Any ideas?

Although PathData contains serializable objects as properties, it does not implement the ISerializable interface itself. The best thing you could do is to encapsulate the properties from PathData in your own Serializable class.

Thanks jaycee, I had gotten too frustrated yesterday with it, so I am doing just that... just seems rather strange they would decide to mark as nonserializable.

And this is all the extra work I had to do... note that if anyone
else needs this in the future, you may want to remove all
code related to pPoint and pRotation, they were for my personal uses...
