XmlSerializer.Serialize Method (Stream, Object)

 

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

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

public void Serialize(
	Stream stream,
	object o
)

Parameters

stream
Type: System.IO.Stream

The Stream used to write the XML document.

o
Type: System.Object

The Object to serialize.

Exception Condition
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 of an object's fields and properties, both public and private, use the BinaryFormatter.

In the stream parameter, specify an object that derives from the abstract Stream class. Classes that derive from Stream 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 Stream object.

using System;
using System.IO;
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 Stream");

      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 FileStream to write with.
      Stream writer = new FileStream(filename, FileMode.Create);
      // Serialize the object, and close the TextWriter
      serializer.Serialize(writer, i);
      writer.Close();
   }
}
