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
)

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.

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

The following example serializes an object using an XmlWriter.

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

// This is the class that will be serialized.
public class OrderedItem
{
   public string ItemName;
   public string Description;
   public decimal UnitPrice;
   public int Quantity;
   public decimal LineTotal;
   // A custom method used to calculate price per item.
   public void Calculate()
   {
      LineTotal = UnitPrice * Quantity;
   }
}
 
public class Test{
   public static void Main()
   {
      Test t = new Test();
      // Write a purchase order.
      t.SerializeObject("simple.xml");
   }
 
   private void SerializeObject(string filename)
   {
      Console.WriteLine("Writing With XmlTextWriter");
 
      XmlSerializer serializer = 
      new XmlSerializer(typeof(OrderedItem));
      OrderedItem i = new OrderedItem();
      i.ItemName = "Widget";
      i.Description = "Regular Widget";
      i.Quantity = 10;
      i.UnitPrice = (decimal) 2.30;
      i.Calculate();
      // Create an XmlTextWriter using a FileStream.
      Stream fs = new FileStream(filename, FileMode.Create);
      XmlWriter writer = 
      new XmlTextWriter(fs, Encoding.Unicode);
      // Serialize using the XmlTextWriter.
      serializer.Serialize(writer, i);
      writer.Close();
   }
