Exemples de sérialisation XML

La sérialisation XML peut prendre plusieurs formes, de la plus simple à la plus complexe. Par exemple, vous pouvez sérialiser une classe qui se compose simplement de champs et de propriétés publics, comme illustré dans Introduction à la sérialisation XML. Les exemples de code suivants abordent différents scénarios avancés, y compris la manière d'utiliser la sérialisation XML pour générer un flux de données XML qui se conforme à un document de schéma XML (XSD) spécifique.

Sérialisation d'un DataSet

En plus de sérialiser une instance d'une classe publique, vous pouvez également sérialiser une instance d'un DataSet, comme illustré dans l'exemple de code suivant :

Private Sub SerializeDataSet(filename As String)
    Dim ser As XmlSerializer = new XmlSerializer(GetType(DataSet))
    ' Creates a DataSet; adds a table, column, and ten rows.
    Dim ds As DataSet = new DataSet("myDataSet")
    Dim t As DataTable = new DataTable("table1")
    Dim c As DataColumn = new DataColumn("thing")
    t.Columns.Add(c)
    ds.Tables.Add(t)
    Dim r As DataRow
    Dim i As Integer
    for i = 0 to 10
        r = t.NewRow()
        r(0) = "Thing " &  i
        t.Rows.Add(r)
    Next
    Dim writer As TextWriter = new StreamWriter(filename)
    ser.Serialize(writer, ds)
    writer.Close()
End Sub

private void SerializeDataSet(string filename)
{
    XmlSerializer ser = new XmlSerializer(typeof(DataSet));

    // Creates a DataSet; adds a table, column, and ten rows.
    DataSet ds = new DataSet("myDataSet");
    DataTable t = new DataTable("table1");
    DataColumn c = new DataColumn("thing");
    t.Columns.Add(c);
    ds.Tables.Add(t);
    DataRow r;

    for (int i = 0; i < 10; i++) {
        r = t.NewRow();
        r[0] = "Thing " + i;
        t.Rows.Add(r);
    }

    TextWriter writer = new StreamWriter(filename);
    ser.Serialize(writer, ds);
    writer.Close();
}

Sérialisation de XmlElement et XmlNode

Vous pouvez également sérialiser les instances d'une classe XmlElement ou XmlNode, comme illustré dans l'exemple de code suivant :

private Sub SerializeElement(filename As String)
    Dim ser As XmlSerializer = new XmlSerializer(GetType(XmlElement))
    Dim myElement As XmlElement = _
    new XmlDocument().CreateElement("MyElement", "ns")
    myElement.InnerText = "Hello World"
    Dim writer As TextWriter = new StreamWriter(filename)
    ser.Serialize(writer, myElement)
    writer.Close()
End Sub

Private Sub SerializeNode(filename As String)
    Dim ser As XmlSerializer = _
    new XmlSerializer(GetType(XmlNode))
    Dim myNode As XmlNode = new XmlDocument(). _
    CreateNode(XmlNodeType.Element, "MyNode", "ns")
    myNode.InnerText = "Hello Node"
    Dim writer As TextWriter = new StreamWriter(filename)
    ser.Serialize(writer, myNode)
    writer.Close()
End Sub

private void SerializeElement(string filename)
{
    XmlSerializer ser = new XmlSerializer(typeof(XmlElement));
    XmlElement myElement = new XmlDocument().CreateElement("MyElement", "ns");
    myElement.InnerText = "Hello World";
    TextWriter writer = new StreamWriter(filename);
    ser.Serialize(writer, myElement);
    writer.Close();
}

private void SerializeNode(string filename)
{
    XmlSerializer ser = new XmlSerializer(typeof(XmlNode));
    XmlNode myNode = new XmlDocument().
    CreateNode(XmlNodeType.Element, "MyNode", "ns");
    myNode.InnerText = "Hello Node";
    TextWriter writer = new StreamWriter(filename);
    ser.Serialize(writer, myNode);
    writer.Close();
}

Sérialisation d'une classe qui contient un champ retournant un objet complexe

Si une propriété ou un champ retourne un objet complexe (tel qu'un tableau ou une instance de classe), XmlSerializer le convertit en élément imbriqué dans le document XML principal. Par exemple, la première classe de l'exemple de code ci-dessous retourne une instance de la deuxième classe :

Public Class PurchaseOrder
    Public MyAddress As Address
End Class

Public Class Address
    Public FirstName As String
End Class

public class PurchaseOrder
{
    public Address MyAddress;
}

public record Address
{
    public string FirstName;
}

La sortie XML sérialisée peut ressembler à ceci :

<PurchaseOrder>
    <MyAddress>
        <FirstName>George</FirstName>
    </MyAddress>
</PurchaseOrder>

Sérialisation d'un tableau d'objets

Vous pouvez également sérialiser un champ qui retourne un tableau d'objets, comme illustré dans l'exemple de code suivant :

Public Class PurchaseOrder
    public ItemsOrders () As Item
End Class

Public Class Item
    Public ItemID As String
    Public ItemPrice As decimal
End Class

public class PurchaseOrder
{
    public Item [] ItemsOrders;
}

public class Item
{
    public string ItemID;
    public decimal ItemPrice;
}

Si deux éléments sont ordonnés, l’instance de classe sérialisée peut ressembler au code suivant :

<PurchaseOrder xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <ItemsOrders>
        <Item>
            <ItemID>aaa111</ItemID>
            <ItemPrice>34.22</ItemPrice>
        </Item>
        <Item>
            <ItemID>bbb222</ItemID>
            <ItemPrice>2.89</ItemPrice>
        </Item>
    </ItemsOrders>
</PurchaseOrder>

Sérialisation d'une classe qui implémente l'interface ICollection

Vous pouvez créer vos propres classes de collection en implémentant l'interface ICollection et en utilisant XmlSerializer pour sérialiser les instances de ces classes.

Imports System.Collections
Imports System.IO
Imports System.Xml.Serialization

Public Class Test
    Shared Sub Main()
        Dim t As Test= new Test()
        t.SerializeCollection("coll.xml")
    End Sub

    Private Sub SerializeCollection(filename As String)
        Dim Emps As Employees  = new Employees()
        ' Note that only the collection is serialized -- not the
        ' CollectionName or any other public property of the class.
        Emps.CollectionName = "Employees"
        Dim John100 As Employee = new Employee("John", "100xxx")
        Emps.Add(John100)
        Dim x As XmlSerializer = new XmlSerializer(GetType(Employees))
        Dim writer As TextWriter = new StreamWriter(filename)
        x.Serialize(writer, Emps)
        writer.Close()
    End Sub
End Class

Public Class Employees

    End Function
End Class

    Public EmpName As String
    Public EmpID As String

    Public Sub New ()
    End Sub

    Public Sub New (newName As String , newID As String )
        EmpName = newName
        EmpID = newID
    End Sub
End Class

using System;

using System.Xml.Serialization;

public class Test

    {
        Test t = new Test();
        t.SerializeCollection("coll.xml");
    }

    private void SerializeCollection(string filename)
    {

        Emps.CollectionName = "Employees";
        Employee John100 = new Employee("John", "100xxx");
        Emps.Add(John100);
        XmlSerializer x = new XmlSerializer(typeof(Employees));
        TextWriter writer = new StreamWriter(filename);
        x.Serialize(writer, Emps);
    }

    }

    public string EmpID;
    
    public Employee() {}

Exemple de bon de commande

Vous pouvez couper et coller l'exemple de code suivant dans un fichier texte et le renommer avec une extension de nom de fichier en .cs ou .vb. Utilisez le compilateur C# ou Visual Basic pour compiler le fichier. Puis exécutez-le à l'aide du nom du fichier exécutable.

Cet exemple utilise un scénario simple pour illustrer comment l'instance d'un objet est créée et sérialisée dans un flux de données de fichier à l'aide de la méthode Serialize. Le flux XML est enregistré dans un fichier. Le même fichier est ensuite lu et reconstruit dans une copie de l’objet d’origine à l’aide de la méthode Deserialize.

Dans cet exemple, une classe nommée PurchaseOrder est sérialisée puis désérialisée. Une deuxième classe nommée Address est également incluse car le champ public nommé ShipTo doit avoir la valeur Address. De la même façon, une classe OrderedItem est incluse car un tableau d'objets OrderedItem doit avoir pour valeur le champ OrderedItems. Enfin, une classe nommée Test contient le code qui sérialise et désérialise les classes.

La méthode CreatePO crée les objets de classe PurchaseOrder, Addresset OrderedItem et définit les valeurs de champs publics. La méthode construit également une instance de la classe XmlSerializer utilisée pour sérialiser et désérialiser PurchaseOrder.

La méthode ReadPo est un peu plus simple. Elle crée juste des objets à désérialiser et lit leurs valeurs. Comme avec la méthode CreatePo, vous devez tout d'abord construire un XmlSerializer, en passant au constructeur le type de classe à désérialiser. De même, un FileStream est requis pour lire le document XML. Pour désérialiser les objets, appelez la méthode Deserialize avec le FileStream en tant qu'argument. L'objet désérialisé doit être converti en une variable d'objet de type PurchaseOrder. Le code lit ensuite les valeurs du PurchaseOrder désérialisé.
