|Currently I am looking for the best solution for object serialization in Windows Phone 7 environment. I will begin my quest with XML Serialization using XmlSerializer Class (popular solution in Silverlight). In this post I will show how to serialize and deserialize objects using XmlSerializer, later I will try to compare several ways of serialization to find out which one is the best.
Creating a sample class
I have created special SampleData class to be serialized and deserialized. It is a very simple class containing only two properties and a constructor declaration for filling down both properties (check code bellow). To control XML generation for a class you can use XmlAttribute, XmlElement, etc. Pay attention that only public properties can be serialized. More information about XML-generation can be found hereand here (MSDN website).
Adding a referenceKeep in mind that XmlSerializer requires System.Xml.Serialization namespace to be added to project. To do so right click the project name and choose Add Reference there. Select System.Xml.Serialization namespace on .NET tab (check image bellow).
SerializationBoth serialization and deserialization processes are very easy to implement. For both operations you will need to create an instance of XmlSerializer class and pass it a type of object for serialization. In addition for serialization you will need a stream object to hold serialized object. To serialize an object simply call Serialize method of XmlSerializer instance. I have created the following method for serialization:
Testing serialization and deserializationI have used the following method to test serialization and deserialization with XmlSerializer. As the result instance of SampleData class after deserialization is exactly the same as the one before the serialization.
Here is how serialized instance of SampleData class looks like:
