Examples

The following example sets the Form property to XmlSchemaForm.Unqualified.

public ref class MyClass
{
public:

   [XmlElement(Form=XmlSchemaForm::Unqualified)]
   String^ ClassName;
};

public class MyClass
{
   [XmlElement(Form = XmlSchemaForm.Unqualified)]
   public string ClassName;
}

Public Class MyClass1
    <XmlElement(Form := XmlSchemaForm.Unqualified)> _
    Public ClassName As String
End Class

Remarks

The Form property determines whether an XML element is qualified or unqualified. The Form property conforms to the World Wide Web Consortium 1999 specification, Namespaces in XML.

If the Namespace property is set to any value, attempting to set the Form property to XmlSchemaForm.Unqualified throws an exception. The default setting, XmlSchemaForm.None, instructs the XmlSerializer to check the schema for the XML document to determine whether the namespace is qualified. If the schema does not specify a value for an individual element or attribute, the XmlSerializer uses the elementFormDefault and attributeFormDefault values to determine whether an element or attribute is qualified. The following XML code shows a schema:

<schema elementFormDefault="qualified"   
attributeFormDefault="unqualified"... >  
 <element name="Name"/>  
 <attribute name="Number"/>  
</schema>  

When the XmlSerializer reads the schema, the Form value for both the Name and Number is XmlSchemaForm.None, but the Name element is qualified, while the Number element is unqualified.
