Serialization of window phone objects

[Wphone] Object serialization

In WP7, data is often used to save data. You can serialize the object to a stream and then save it to a file.

There are three common serialization Methods: XML, JSON, and datacontract.

The following describes the use of three types of serialization.

First, define a serialization class person

        public class Person        {            public string Name { get; set; }            public int Age { get; set; }        }

1. Use xmlserializer for serialization

The system. xml. serialization library must be referenced.

Person = new person () {name = "BoMo", age = 20}; // start memorystream MS = new memorystream (); xmlserializer xml = new xmlserializer (typeof (person); XML. serialize (MS, person); // key code for XML serialization byte [] arr = Ms. toarray (); Ms. close (); string xmlstring = encoding. utf8.getstring (ARR, 0, arr. length); MessageBox. show (xmlstring. length. tostring (); // XML deserialization memorystream MS2 = new memorystream (encoding. utf8.getbytes (xmlstring); xmlserializer xml2 = new xmlserializer (typeof (person); person Ptest = xml. deserialize (MS2) as person; // key code of XML deserialization ms2.close ();

 

2. Use JSON

The system. servicemodel. Web library must be referenced.

Serialize the object to the stream and convert it to a JSON string.

During deserialization, the string is read to the stream before deserialization.

Person = new person () {name = "BoMo", age = 20}; // serialize string jsonstring; using (var ms = new memorystream ()) {New datacontractjsonserializer (p1.gettype ()). writeobject (MS, person); jsonstring = encoding. utf8.getstring (Ms. toarray (), 0, (INT) ms. length); MessageBox. show (jsonstring. length. tostring ();} // deserialization of using (var ms = new memorystream (encoding. utf8.getbytes (jsonstring) {person desp = (person) New datacontractjsonserializer (typeof (person )). readobject (MS );}

 

3. Use datacontract for serialization

The system. runtime. serialization library needs to be referenced. The steps are similar to those in JSON format.

Person p1 = new person () {name = "BoMo", age = 28}; // datacontract serialize memorystream MS = new memorystream (); datacontractserializer SER = new datacontractserializer (typeof (person); Ser. writeobject (MS, P1); byte [] array = Ms. toarray (); Ms. close (); string _ serializestring = encoding. utf8.getstring (array, 0, array. length); MessageBox. show (_ serializestring. length. tostring (); // deserialize datacontractserializer ser2 = new datacontractserializer (typeof (person); memorystream MS2 = new memorystream (encoding. utf8.getbytes (_ serializestring); person P2 = ser2.readobject (MS2) as person;

 

In the preceding three methods, the maximum string, the slowest speed, the fastest JSON, and the smallest volume are serialized in XML.

JSON is recommended for Object serialization.
