XmlTextAttribute, constructeur ()
Assembly : System.Xml (dans system.xml.dll)
Vous pouvez substituer la manière dont XmlSerializer sérialise un champ public ou une propriété de lecture/écriture publique en créant XmlAttributes et en affectant XmlTextAttribute à sa propriété XmlText. Pour plus d'informations, consultez la classe XmlAttributeOverrides.
L'exemple suivant sérialise une classe qui contient un champ public nommé Comment. L'exemple applique XmlTextAttribute au champ pour qu'il ne soit pas sérialisé en tant qu'élément XML mais en tant que texte XML.
using System; using System.IO; using System.Xml.Serialization; using System.Xml.Schema; using System.Xml; public class Group { public string GroupName; public string Comment; } public class Test { public static void Main() { Test t = new Test(); t.SerializerOrder("TextOverride.xml"); } /* Create an instance of the XmlSerializer class that overrides the default way it serializes an object. */ public XmlSerializer CreateOverrider() { /* Create instances of the XmlAttributes and XmlAttributeOverrides classes. */ XmlAttributes attrs = new XmlAttributes(); XmlAttributeOverrides xOver = new XmlAttributeOverrides(); /* Create an XmlTextAttribute to override the default serialization process. */ XmlTextAttribute xText = new XmlTextAttribute(); attrs.XmlText = xText; // Add the XmlAttributes to the XmlAttributeOverrides. xOver.Add(typeof(Group), "Comment", attrs); // Create the XmlSerializer, and return it. XmlSerializer xSer = new XmlSerializer(typeof(Group), xOver); return xSer; } public void SerializerOrder(string filename) { // Create an XmlSerializer instance. XmlSerializer xSer = CreateOverrider(); // Create the object and serialize it. Group myGroup = new Group(); myGroup.Comment = "This is a great product."; TextWriter writer = new StreamWriter(filename); xSer.Serialize(writer, myGroup); } }
