Serializing and deserializing entity instances

Serialization is defined as the process of converting an object into a stream of bytes (as a memory stream) so that it can be persisted in the memory or to a permanent storage device such as a database or a file. You can serialize or deserialize an entity instance using ObjectContext. To do this, you need to call the Serialize or the Deserialize method of the BinaryFormatter class as shown in the following code snippets:

public static void Serialize(sString fileName, oObject obj)
        BinaryFormatter var binaryFormatter = new 
        FileStreamvar fileStream = new 
                binaryFormatter.Serialize(fileStream, obj);

            catch (SerializationException ex)
                throw new ApplicationException("The object graph 
                could not be serialized", ex);
