CP-15504: Having problems with Serialize and Deserialize using GraphML #96

Hi,   I am new in Quick Graph and trying to Serialize and Deserialize but I'm currently having problems with it. Here is the overall scenario. I am generating a route from shape file data using dijkstra algorithm and undirected graph object. This is working but it is providing me severe performance problems. I planned to prepare and serialize a set of undirected graph object and edge factory object so that I can deserialize the same for routing and hopefully resolve the performance issue.   First, I tried to use .NET serialization and deserialization for these two objects. When I tried this approach, the serialization and deserialization seems to happen but upon using the deserialized undirected graph object and edgeCost object, I get "The given key was not present in the dictionary" error.   Second, I tried to do serialization and deserialization using GraphML options in QuickGraph but received the following error below.  

The type 'QuickGraph.UndirectedGraph<int,QuickGraph.Edge<int>>' cannot be used as type parameter 'TGraph' in the generic type or method 'QuickGraph.Serialization.GraphMLExtensions.DeserializeFromGraphML<TVertex,TEdge,TGraph>(TGraph, System.Xml.XmlReader, QuickGraph.IdentifiableVertexFactory<TVertex>, QuickGraph.IdentifiableEdgeFactory<TVertex,TEdge>)'. There is no implicit reference conversion from 'QuickGraph.UndirectedGraph<int,QuickGraph.Edge<int>>' to 'QuickGraph.IMutableVertexAndEdgeListGraph<int,QuickGraph.Edge<int>>'.

  I have created a small sample to shows these issues. Any input in this regard will be very helpful. If you feel I should take a completely different approach for the performance problem, please let me know.   Sample Code is attached with this Issue   Regards,   Sudip

hello barman, did you manage to serialize or deserialize your UndirectedGraph?

I'm having the same issues as you did.
