XmlAttributes.XmlType Property

Definition

Gets or sets an object that specifies how the XmlSerializer serializes a class to which the XmlTypeAttribute has been applied.

public System.Xml.Serialization.XmlTypeAttribute XmlType { get; set; }
public System.Xml.Serialization.XmlTypeAttribute? XmlType { get; set; }

Property Value

An XmlTypeAttribute that overrides an XmlTypeAttribute applied to a class declaration.

Examples

The following example creates an XmlTypeAttribute object, and assigns it to the XmlType property of an XmlAttributes object.

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

public class Transportation
{
   public Car[] Cars;
}

public class Car
{
   public int ID;
}

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

   // Return an XmlSerializer used for overriding.
   public XmlSerializer CreateOverrider()
   {
      // Create the XmlAttributes and XmlAttributeOverrides objects.
      XmlAttributes attrs = new XmlAttributes();
      XmlAttributeOverrides xOver = new XmlAttributeOverrides();

      /* Create an XmlTypeAttribute and change the name of the
         XML type. */
      XmlTypeAttribute xType = new XmlTypeAttribute();
      xType.TypeName = "Autos";

      // Set the XmlTypeAttribute to the XmlType property.
      attrs.XmlType = xType;

      /* Add the XmlAttributes to the XmlAttributeOverrides,
         specifying the member to override. */
      xOver.Add(typeof(Car), attrs);

      // Create the XmlSerializer, and return it.
      XmlSerializer xSer = new XmlSerializer
      (typeof(Transportation), xOver);
      return xSer;
   }

   public void SerializeObject(string filename)
   {
      // Create an XmlSerializer instance.
      XmlSerializer xSer = CreateOverrider();

      // Create object and serialize it.
      Transportation myTransportation =
      new Transportation();

      Car c1 = new Car();
      c1.ID = 12;

      Car c2 = new Car();
      c2.ID = 44;

      myTransportation.Cars = new Car[2]{c1,c2};

      // To write the file, a TextWriter is required.
      TextWriter writer = new StreamWriter(filename);
      xSer.Serialize(writer, myTransportation);
   }
}

Remarks

The XmlTypeAttribute can be used to control how a type is serialized by the XmlSerializer. For example, by default, when a type is serialized, the XmlSerializer uses the class name as the XML element name. By creating an XmlTypeAttribute, setting the XmlType property to it, and creating an XmlAttributeOverrides object, you can change the XML element name.
