XmlSerializer Constructor (Type)

Initializes a new instance of the XmlSerializer class that can serialize objects of the specified type into XML documents, and deserialize XML documents into objects of the specified type.

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

public XmlSerializer (
	Type type
)
public XmlSerializer (
	Type type
)
public function XmlSerializer (
	type : Type
)

Parameters

type

The type of the object that this XmlSerializer can serialize.

Commonly, an application defines several classes that the XmlSerializer converts into a single XML-instance document. However, the XmlSerializer must know only one type--the type of the class that represents the XML root element. The XmlSerializer automatically serializes all subordinate class instances. Similarly, only the type of the XML root element is required for deserialization.

The following example constructs an XmlSerializer that serializes a simple object named Widget. The example sets various properties of the object before calling the Serialize method.

private void SerializeObject(string filename)
{
   XmlSerializer serializer = 
   new XmlSerializer(typeof(OrderedItem));

   // Create an instance of the class to be serialized.
   OrderedItem i = new OrderedItem();

   // Set the public property values.
   i.ItemName = "Widget";
   i.Description = "Regular Widget";
   i.Quantity = 10;
   i.UnitPrice = (decimal) 2.30;

   // Writing the document requires a TextWriter.
   TextWriter writer = new StreamWriter(filename);

   // Serialize the object, and close the TextWriter.
   serializer.Serialize(writer, i);
   writer.Close();
}

// This is the class that will be serialized.
public class OrderedItem
{
   public string ItemName;
   public string Description;
   public decimal UnitPrice;
   public int Quantity;
}


private void SerializeObject(String filename)
{
    XmlSerializer serializer =
        new XmlSerializer(OrderedItem.class.ToType());

    // Create an instance of the class to be serialized.
    OrderedItem i = new OrderedItem();

    // Set the public property values.
    i.itemName = "Widget";
    i.description = "Regular Widget";
    i.quantity = 10;
    i.unitPrice = Convert.ToDecimal(2.3);

    // Writing the document requires a TextWriter.
    TextWriter writer = new StreamWriter(filename);

    // Serialize the object, and close the TextWriter.
    serializer.Serialize(writer, i);
    writer.Close();
} //SerializeObject

// This is the class that will be serialized.
public class OrderedItem
{
    public String itemName;
    public String description;
    public System.Decimal unitPrice;
    public int quantity;
} //OrderedItem
