Hello all...
Im doing some work with Graph, so create some clases:
Node Arc Graph.
(A Graph is a list of Nodes)
I like the idea about been able to save/load a graph to/from disk. Im trying to XmlSerialize my graph.
I have define my graph so, that this cannot be made, becouse:
1.- Node = { X, Y, ListOfOutgoingArcs }
2.- Arc = { StartNode, StopNode, Weight}This definition is circular....
What do u think is the best to modify, for let the graph been saved to disk?
When i run this, i get this:
<mono1.0.5>
System.InvalidOperationException: A cirtular reference was detected while serializing an object of type Node
</mono>
thanks in advance,
