I have a complex "query" object that I need to save to a table and then
restore.  Everything works great with the following exception.  When I try
to create a method within the object called Restore() and try to restore the
object onto itself I can't:  Here's the code segment:

         byte[] b = Convert.FromBase64String(SavedObjectString);
         MemoryStream ms = new MemoryStream(b);
         BinaryFormatter bf = new BinaryFormatter();

         this = (query)bf.Deserialize(ms);

As you may know the "this" reference is read-only....yet I want to be able
to restore the object within itself.  Is there a way to do this?

I have successfully restored the object by applying an instance variable:

        query oQuery = new query();

         byte[] b = Convert.FromBase64String(SavedObjectString);
         MemoryStream ms = new MemoryStream(b);
         BinaryFormatter bf = new BinaryFormatter();

         oQuery = (query)bf.Deserialize(ms);

But the above code must be executed in another class so its not as helpful
as it could be if I could incorporate it into my query class.

Thanks in advance.
