c# XML序列化Observable集合

我正试图反序列化一堆由旧版本的代码序列化的数据。当数据被序列化时，类具有与当前类结构不同的结构。为了让这个数据在我的新代码中工作，我不得不将旧的类结构添加到代码中，以便导入这个序列化的数据。我把这个类称为class _oldVersions。为了反序列化，我使用以下代码:

className_oldVersions temp_className = new className_oldVersions();
XmlSerializer testSerializer = new XmlSerializer(typeof(className_oldVersions), 
   new XmlRootAttribute { ElementName = "className" });
temp_className = (ObservedData_OldVersions)testSerializer.Deserialize(ms_MemoryStream);

这段代码工作得很好，并且我可以使用与原始类名不同的类名来反序列化数据。我的问题是，当我试图使用相同的过程来反序列化一个可观察集合。

我创建了一个重现我的问题的代码。在这段代码中，我序列化了OptimizationVariables类的一个可观察集合，并且我想反序列化为OptimizationVariablies_NewClass类的一个可观察集合，该集合具有与原始结构相似的结构。
