XmlRootAttribute Constructor ()

 

Initializes a new instance of the XmlRootAttribute class.

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

public:
XmlRootAttribute()

The following example creates an instance of an XmlRootAttribute and assigns it to the XmlRoot property of an XmlAttributes object. When the XmlSerializer serializes the MyClass object, it uses the XmlRootAttribute object to override the default root element.

#using <System.Xml.dll>
#using <System.dll>

using namespace System;
using namespace System::IO;
using namespace System::Xml::Serialization;

// This is the class that is the default root element.
public ref class MyClass
{
public:
   String^ Name;
};

XmlSerializer^ CreateOverrider();
void SerializeOrder( String^ filename )
{
   // Create an XmlSerializer instance using the method below.
   XmlSerializer^ xSer = CreateOverrider();

   // Create the object, and set its Name property.
   MyClass^ myClass = gcnew MyClass;
   myClass->Name = "New Class Name";

   // Serialize the class, and close the TextWriter.
   TextWriter^ writer = gcnew StreamWriter( filename );
   xSer->Serialize( writer, myClass );
   writer->Close();
}

// Return an XmlSerializer to override the root serialization.
XmlSerializer^ CreateOverrider()
{
   // Create an XmlAttributes to override the default root element.
   XmlAttributes^ attrs = gcnew XmlAttributes;

   // Create an XmlRootAttribute and set its element name and namespace.
   XmlRootAttribute^ xRoot = gcnew XmlRootAttribute;
   xRoot->ElementName = "OverriddenRootElementName";
   xRoot->Namespace = "http://www.microsoft.com";

   // Set the XmlRoot property to the XmlRoot object.
   attrs->XmlRoot = xRoot;
   XmlAttributeOverrides^ xOver = gcnew XmlAttributeOverrides;

   /* Add the XmlAttributes object to the 
      XmlAttributeOverrides object. */
   xOver->Add( MyClass::typeid, attrs );

   // Create the Serializer, and return it.
   XmlSerializer^ xSer = gcnew XmlSerializer( MyClass::typeid,xOver );
   return xSer;
}

int main()
{
   SerializeOrder( "OverrideAttribute.xml" );
}
