XmlTypeAttribute Constructor (String)


The .NET API Reference documentation has a new home. Visit the .NET API Browser on docs.microsoft.com to see the new experience.

Initializes a new instance of the XmlTypeAttribute class and specifies the name of the XML type.

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

public XmlTypeAttribute(
	string typeName


Type: System.String

The name of the XML type that the XmlSerializer generates when it serializes the class instance (and recognizes when it deserializes the class instance).

Apply the XmlTypeAttribute to a class to specify the XML type's namespace, the XML type name, and whether to include the type in the XML schema document. To see the results of setting the properties of the XmlTypeAttribute class, compile your application as an executable or DLL, and pass the resulting file to the XML Schema Definition Tool (Xsd.exe). The tool writes the schema, including the type definition.

The following example creates two instances of the XmlTypeAttribute class that are used to override the serialization of the two classes.

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

public class Person
   public string personName;
   public Address address;
public class Address
   public string state;
   public string zip;

public class PersonTypeAttribute
   public static void Main()
      PersonTypeAttribute myPersonTypeAttribute= new PersonTypeAttribute();

   public XmlSerializer CreateOverrider()
      XmlAttributeOverrides personOverride = new XmlAttributeOverrides();      

      XmlAttributes personAttributes = new XmlAttributes();      
      XmlTypeAttribute personType = new XmlTypeAttribute();
      personType.TypeName = "Employee";
      personType.Namespace = "http://www.microsoft.com";
      personAttributes.XmlType = personType;

      XmlAttributes addressAttributes = new XmlAttributes();
      // Create 'XmlTypeAttribute' with 'TypeName' as an argument.
      XmlTypeAttribute addressType = new XmlTypeAttribute("Address");
      addressType.Namespace = "http://www.microsoft.com";

      personOverride.Add(typeof(Person) ,personAttributes);

      XmlSerializer myXmlSerializer = new XmlSerializer
         (typeof(Person), personOverride);
      return myXmlSerializer;

   public void SerializeObject(string filename)
      XmlSerializer myXmlSerializer = CreateOverrider();

      Address myAddress = new Address();

      Person myPerson = new Person();
      // Serialize to a file.
      TextWriter writer = new StreamWriter(filename);
      myXmlSerializer.Serialize(writer, myPerson);
