Provides data for the UnknownNode event.

Namespace:   System.Xml.Serialization
Assembly:  System.Xml (in System.Xml.dll)

System.Object
  System.EventArgs
    System.Xml.Serialization.XmlNodeEventArgs

public class XmlNodeEventArgs : EventArgs

NameDescription
System_CAPS_pubpropertyLineNumber

Gets the line number of the unknown XML node.

System_CAPS_pubpropertyLinePosition

Gets the position in the line of the unknown XML node.

System_CAPS_pubpropertyLocalName

Gets the XML local name of the XML node being deserialized.

System_CAPS_pubpropertyName

Gets the name of the XML node being deserialized.

System_CAPS_pubpropertyNamespaceURI

Gets the namespace URI that is associated with the XML node being deserialized.

System_CAPS_pubpropertyNodeType

Gets the type of the XML node being deserialized.

System_CAPS_pubpropertyObjectBeingDeserialized

Gets the object being deserialized.

System_CAPS_pubpropertyText

Gets the text of the XML node being deserialized.

NameDescription
System_CAPS_pubmethodEquals(Object)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_protmethodFinalize()

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_protmethodMemberwiseClone()

Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

For more information about handling events, see NIB: Consuming Events.

The UnknownNode event can occur only when you call the Deserialize method.

The following example uses the UnknownNode event of the XmlSerializer to print various properties of an unknown XML node that is encountered when calling the XmlSerializer class's Deserialize method.

using System;
using System.IO;
using System.Xml;
using System.Xml.Serialization;

public class Group{
   // Only the GroupName field will be known.
   public string GroupName;
}

public class Test{
   static void Main(){
      Test t = new Test();
      t.DeserializeObject("UnknownNodes.xml");
   }

   private void DeserializeObject(string filename){
      XmlSerializer mySerializer = new XmlSerializer(typeof(Group));
      FileStream fs = new FileStream(filename, FileMode.Open);
      mySerializer.UnknownNode += new 
      XmlNodeEventHandler(serializer_UnknownNode);
      Group myGroup = (Group) mySerializer.Deserialize(fs);
      fs.Close();
   }
   private void serializer_UnknownNode
   (object sender, XmlNodeEventArgs e){
      Console.WriteLine
      ("UnknownNode Name: {0}", e.Name);
      Console.WriteLine
      ("UnknownNode LocalName: {0}" ,e.LocalName);
      Console.WriteLine
      ("UnknownNode Namespace URI: {0}", e.NamespaceURI);
      Console.WriteLine
      ("UnknownNode Text: {0}", e.Text);

      XmlNodeType myNodeType = e.NodeType;
      Console.WriteLine("NodeType: {0}", myNodeType);

      Group myGroup = (Group) e.ObjectBeingDeserialized;
      Console.WriteLine("GroupName: {0}", myGroup.GroupName);
      Console.WriteLine();
   }
}
