XmlSerializer.Serialize Method (TextWriter, Object)

 

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

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

public void Serialize(
	TextWriter textWriter,
	object o
)

Parameters

textWriter
Type: System.IO.TextWriter

The TextWriter used to write the XML document.

o
Type: System.Object

The Object to serialize.

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 textWriter parameter, specify an object that derives from the abstract TextWriter class. Classes that derive from TextWriter include:

System_CAPS_noteNote

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

The following example serializes an object using a TextWriter.

using System;
using System.IO;
using System.Text;
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(string[] args)
   {
      Test t = new Test();
      // Write a purchase order.
      t.SerializeObject("simple.xml");
   }

  private void SerializeObject(string filename)
  {
      Console.WriteLine("Writing With TextWriter");

      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 a StreamWriter to write with. First create a FileStream
         object, and create the StreamWriter specifying an Encoding to use. */
      FileStream fs = new FileStream(filename, FileMode.Create);
      TextWriter writer = new StreamWriter(fs, new UTF8Encoding());
      // Serialize using the XmlTextWriter.
      serializer.Serialize(writer, i);
      writer.Close();
   }
}
