  1. POSerialization and Deserialization When References Are Involved in C#
    text
    copied!<p>I have a singleton class called Manager that holds a list of object instances:</p> <pre><code>static class Manager { static List&lt;Foo&gt; Foos = new List&lt;Foo&gt;(); } </code></pre> <p>I then have a collection of object instances using a class called Meter that uses references to items in the list Foos:</p> <pre><code>class Meter { public Foo MyFoo = null; } ... public void CreateMeter(int UserChoice) { Meter MyMeter = new Meter(); MyMeter.MyFoo = Manager.Foos[UserChoice]; } </code></pre> <p>When the application saves a project file it serializes the instances of Foo in Foos along with all the instances of Meter.</p> <p>My problem is how to deserialize this arrangement. Currently I do the following:</p> <ul> <li>Deserialize the project-wide instances of Foo to reconstruct Manager.Foos</li> <li>Deserialize a meter instance which includes an instance of Foo for the MyFoo property</li> <li>Search Manager.Foos and find the matching reference for MyMeter.MyFoo and then assign the reference from Manager.Foos.</li> </ul> <p>This seems to me clunky and not too easy to extend. I would rather that the Meter factory doesn't need to search Manager.Foos during deserialization because in future Meter might take it's refence to a Foo instance from other places, not just Manager.</p> <p>Is there a simple but flexible alternative solution to this deserialization problem where references to objects can be easily reconstructed?</p>
