So I'm trying to serialize and deserialize an object called player in my xamarin forms project. and thats what Player looks like:
public class Player
{
//stores weather the player ended his turn
public bool turnOver = false;
//the name of the player
public string name { get; set; }
//total score of the player
public long score { get; set; }
//coins to buy abillities
public int coins { get; set; }
//array that stores for each ability how much uses left
public int[] abilities = { 2, 2, 2, 2 };
//the levels the player have completed
public List<long> completedLevels;
//player constructor that initializes all the data for initial use
public Player()
{
this.name = "";
score = 0;
coins = 100;
completedLevels = new List<long>();
}
}
I used these methods in the Android project to serialize and deserialize the object.
public void Serialize<T>(Player list)
{
//Creating XmlSerializer.
XmlSerializer serializer = new XmlSerializer(typeof(T));
var documentsPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.Personal);
var filePath = Path.Combine(documentsPath, "data1.xml");
var file = File.Open(filePath, FileMode.OpenOrCreate, FileAccess.Write);
var strm = new StreamWriter(file);
//Convert the XML to List
serializer.Serialize(strm, list);
strm.Close();
}
public T GenericDeSerialize<T>()
{
//Creating XmlSerializer for the object
XmlSerializer serializer = new XmlSerializer(typeof(T));
var documentsPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.Personal);
var filePath = Path.Combine(documentsPath, "data1.xml");
var file = File.Open(filePath, FileMode.OpenOrCreate, FileAccess.Read);
var strm = new StreamReader(file);
string text = strm.ReadToEnd();
//Deserialize back to object from XML
T b = (T)serializer.Deserialize(strm);
strm.Close();
return b;
}
Now the serialize part goes well but when trying to deserialize I get the Exception:
Root element is missing
I took a look at the generated xml and it looks like that:
<?xml version="1.0" encoding="utf-8"?>
<Player xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<turnOver>false</turnOver>
<abilities>
<int>2</int>
<int>2</int>
<int>2</int>
<int>2</int>
</abilities>
<completedLevels />
<name />
<score>0</score>
<coins>500</coins>
</Player>
I can't find the problem with this can anyone point out why xmlserializer may be writing something and couldn't read it? Thanks
Edit: Here is how I call them for testing right now serializer is the class that have the two functions.
Serializer ser = new Serializer();
Player p = new Player();
p.coins = 500;
ser.Serialize<Player>(p);
ser.GenericDeSerialize<Player>();
