// Called by the framework when user opens a Petrel project file

using (FileStream file = fileInfo.OpenRead())
{
BinaryFormatter bf = new BinaryFormatter();
this.customObjectsDictionary = bf.Deserialize(file) as Hashtable;
}

// Called by the framework when user saves a Petrel project file
public void Save()

using (FileStream fileStream = fileInfo.OpenWrite())
{
BinaryFormatter bf = new BinaryFormatter();
bf.Serialize(fileStream, this.customObjectsDictionary);
}
}
}
The Add() function is used to store IIdentifiable objects and its droid in a hashtable. Open()
deserializes a binary file in order to fill the hashtable and Save() serializes the hashtable into a file
stream.
4. Important notes about serialization
There are two very important remarks to be done about serialization:
1) 1. If a custom domain object contains references to other Petrel domain objects, it must serialize
only the Droid’s of such references and not the objects themselves. Observe the example below:
[NonSerialized]
private SeismicCube internalSeismicCube;
private Droid seismicCubeDroid;
2) 2. Before calling the serialization (CustomDataSource.Save() method), any events on the objects to
be serialized must be turned off.
obj.Changed -= this .changedEventHandler;
Such events must probably be linked again after the serialization has finished executing.
