    //The BinaryFormatter used above is very effective and generates a very concise byte stream.    //All objects serialized by this formatter can also be deserialized through this formatter, which makes this tool ideal for serializing objects that will be deserialized on the .NET Framework.    //It should be noted that the constructor is not called when deserializing an object.  This constraint is imposed on deserialization for performance reasons.    // However, this violates some common conventions between the runtime library and the object writer, and developers should make sure they understand the consequences when marking the object as serializable.    // If portability is required, switch to SoapFormatter.    //Simply use SoapFormatter instead of the BinaryFormatter in the above code,    //And call Serialize and Deserialize as before.  This formatter generates the following output for the example used above.  }
