How can I deserialize an XML - Windows Phone

Valentin Martin

12y1.7kC#

I'm using this function to deserialise the data of the xml file:

Uri uri = new Uri("/XML/ligne1_EUROPE.xml", UriKind.Relative);
XDocument document = XDocument.Load("XML/ligne1_EUROPE.xml"); 
XmlSerializer serializer = new XmlSerializer(typeof(Destinataires)); 
Destinataires ArretLoad = (Destinataires)serializer.Deserialize(document.CreateReader());
listBox.ItemsSource = ArretLoad.Collection;

He call the Destinataires class:

[XmlRoot("root")] 
   public class Destinataires 
   { 
      [XmlArray("Destinataires")] 
      [XmlArrayItem("Destinataire")] 
      [XmlArrayItem("Horraires")] 
      [XmlArrayItem("Horraire")] 
      public ObservableCollection<XML_Arret> Collection { get; set; } 
   }
And call the XML_Arret class
 public class XML_Arret 
 { 
   [XmlElement("Designation")] 
   public string Designation { get; set; } 
   [XmlElement("Carre")] 
   public string Carre { get; set; } 
   [XmlElement("Horraires")] 
   public Horraires[] Horaires { get; set; } 
 
   public class Horraires 
   { 
      [XmlElement("Horraire")] 
      public string Horraire { get; set; } 
   } 
}
My XML files is:
xml version="1.0" encoding="ISO-8859-1"?>

                  ...       
          
               
         ...   
    
</root>
But when I debug my programm, I've this message: 
   Une exception de type 'System.InvalidOperationException' s'est produite dans System.Xml.Serialization.ni.dll 
   mais n'a pas été gérée dans le code utilisateur 
   
   à la ligne: XmlSerializer serializer = new XmlSerializer(typeof(Destinataires));
So, I'm lost, Do you can Help me?
And I'm sorry for my langage, I'm a french person.
Thanks

Accepted answer
Valentin,

I think the problem here is that your XML attributes are not quite.

When I changed them to the following, your file deserialized correctly:

[XmlRoot("root")]
public class Destinataires
{
[XmlArray("Destinataires")]
[XmlArrayItem("Destinataire")]
public ObservableCollection Collection { get; set; }
}

public class XML_Arret
{
[XmlElement("Designation")]
public string Designation { get; set; }
[XmlElement("Carre")]
public string Carre { get; set; }
[XmlArray("Horraires")]
[XmlArrayItem("Horraire")]
public Horraires[] Horaires { get; set; }

public class Horraires
{
[XmlText]
public string Horraire { get; set; }
}
}

Hi,

I've try with your changement:

XmlSerializer deserializer = new XmlSerializer(typeof(DestinatairesList));
TextReader reader = new StreamReader("XML/ligne1_EUROPE.xml");
object obj = deserializer.Deserialize(reader);
DestinatairesList XmlData = (DestinatairesList)obj;
reader.Close();

And for display Destinataire. Designation in my ListBox:
listBox1.ItemsSource = XmlData.Destinataire; ???

And:

[XmlRoot("Destinataires")]
public class DestinatairesList
{
[XmlElement("Destinataires")]
public List Destinataire { get; set; }
}

public class Destinataire
{
[XmlElement("Destinataire")]
public string DestinatairE { get; set; }
[XmlElement("Designation")]
public string Designation { get; set; }
[XmlElement("Carre")]
public string Carre { get; set; }
[XmlElement("Horraires")]
public List Horaires { get; set; }
}

public class Horraires
{
[XmlElement("Horraire")]
public string Horaire { get; set; }
}

But I've a problem: nothing appears on my screen. So I think I've a problem when I sent my data to the ListBox, or is in the DestinatairesList or Destinataire.

Hey Sorry Valentin,

Now I understood your problem you want do deserialize even the child nodes right ?

can you give try in this way

[Serializable()]
[System.Xml.Serialization.XmlRootAttribute(Namespace = "", IsNullable = false, ElementName = "rootnode")]
public partial class RootNode
{

[System.Xml.Serialization.XmlElementAttribute("collection1")]
public List OuterCollections { get; set; }
}

[Serializable()]
public partial class OuterCollection
{

[XmlAttribute("attribute1")]
public string attribute1 { get; set; }

[XmlArray(ElementName = "innercollection1")]
[XmlArrayItem("text", Type = typeof(InnerCollection1))]
public List innerCollection1Stuff { get; set; }

[XmlArray("innercollection2")]
[XmlArrayItem("text", typeof(InnerCollection2))]
public List innerConnection2Stuff { get; set; }
}

[Serializable()]
public partial class InnerCollection2
{

[XmlText()]
public string text { get; set; }
}

public partial class InnerCollection1
{

[XmlText()]
public int number { get; set; }
}

Hello Valentine,

Can you try it in this way

[Serializable()]
public class Car
{
[System.Xml.Serialization.XmlElement("StockNumber")]
public string StockNumber { get; set; }

[System.Xml.Serialization.XmlElement("Make")]
public string Make { get; set; }

[System.Xml.Serialization.XmlElement("Model")]
public string Model { get; set; }
}

[Serializable()]
[System.Xml.Serialization.XmlRoot("CarCollection")]
public class CarCollection
{
[XmlArray("Cars")]
[XmlArrayItem("Car", typeof(Car))]
public Car[] Car { get; set; }
}
The Deserialize function:

CarCollection cars = null;
string path = "cars.xml";

XmlSerializer serializer = new XmlSerializer(typeof(CarCollection));

StreamReader reader = new StreamReader(path);
cars = (CarCollection)serializer.Deserialize(reader);
reader.Close();
And the slightly tweaked xml (I needed to add a new element to wrap ...Net is picky about deserializing arrays):

1020
Nissan
Sentra

1010
Toyota
Corolla

1111
Honda
Accord
