XmlSerializer.Serialize Method (XmlWriter, Object)

Serializes the specified Object and writes the XML document to a file using the specified XmlWriter.

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

public:
void Serialize (
	XmlWriter^ xmlWriter, 
	Object^ o
)
public void Serialize (
	XmlWriter xmlWriter, 
	Object o
)
public function Serialize (
	xmlWriter : XmlWriter, 
	o : Object
)
Not applicable.

Parameters

xmlWriter

The XmlWriter used to write the XML document.

o

The Object to serialize.

Exception typeCondition

InvalidOperationException

An error occurred during serialization. The original exception is available using the InnerException property.

The Serialize method converts the public fields and read/write properties of an object into XML. It does not convert methods, indexers, private fields, or read-only properties. To serialize all an object's fields and properties, both public and private, use the BinaryFormatter.

In the xmlWriter parameter, specify an object that derives from the abstract XmlWriter class. The XmlTextWriter derives from the XmlWriter.

NoteNote:

The XmlSerializer cannot serialize the following: arrays of ArrayList and arrays of List.

The following example serializes an object using an XmlWriter.

#using <System.Xml.dll>

   int Quantity;
   Decimal LineTotal;

   // A custom method used to calculate price per item.
   void Calculate()
   {
      LineTotal = UnitPrice * Quantity;
   }
};

void SerializeObject( String^ filename )
{
   Console::WriteLine( "Writing With XmlTextWriter" );
   XmlSerializer^ serializer = gcnew XmlSerializer( OrderedItem::typeid );
   OrderedItem^ i = gcnew OrderedItem;
   i->ItemName = "Widget";

   i->Quantity = 10;

   // Create an XmlTextWriter using a FileStream.
   Stream^ fs = gcnew FileStream( filename,FileMode::Create );
   XmlWriter^ writer = gcnew XmlTextWriter( fs,Encoding::Unicode );

   // Serialize using the XmlTextWriter.
   serializer->Serialize( writer, i );
   writer->Close();
