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)

'Declaration
Public Sub New ( _
	type As Type _
)

Parameters

type
Type: System.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 an object named Widget. The example sets various properties of the object before calling the Serialize method.

Private Sub SerializeObject(ByVal filename As String)
    Dim serializer As New XmlSerializer(GetType(OrderedItem))

    ' Create an instance of the class to be serialized. 
    Dim i As New OrderedItem()

    ' Set the public property values. 
    With i
        .ItemName = "Widget"
        .Description = "Regular Widget"
        .Quantity = 10
        .UnitPrice = CDec(2.3)
    End With 

    ' Writing the document requires a TextWriter. 
    Dim writer As New StreamWriter(filename)

    ' Serialize the object, and close the TextWriter.
    serializer.Serialize(writer, i)
    writer.Close()
End Sub 


' This is the class that will be serialized. 
Public Class OrderedItem
    Public ItemName As String 
    Public Description As String 
    Public UnitPrice As Decimal 
    Public Quantity As Integer 
End Class
