How to save this object to file

[MrNorth]

Im my endeavour to create an object framework for a project, I have come to the conclusion that I need to add a "savefile" method to my CDocumentCollection class

This is a simple class.. it inherits collectionbase and contains an array with simple CDocument objects.

I want to do something like this

dim mycollection as new CDocumentCollection
 
mycollection.add(new CDocument("Doc1"))
mycollection.add(new CDocument("Doc3"))
mycollection.add(new CDocument("Doc14"))
mycollection.add(new CDocument("Doc156"))
 
mycollection.SaveToFile("c:\myfile.gps")

Is there an easy way to save the object hieararchy to binary file and an easy way to load it the same way? Im sure there are many programs in vb.net /C# that perform this simple thing... I just want to learn the "right" way to do it...

dim mycollection as new CDocumentCollection
mycollection = mycollection.LoadFromFile("c:\myfile.gps")

I have very little experience in these things, are there any patterns or rules to follow to make this a good design? I know a little about serialization... I have read it is a good way to save/load binary config files... can this help me? How do I proceed?

kind regards
Henrik
