How to: Read Object Data from an XML File (C# and Visual Basic)
This example reads object data that was previously written to an XML file using the XmlSerializer class.
This code example is also available as an IntelliSense code snippet. In the code snippet picker, it is located in XML. For more information, see Code Snippets.
Public Class Book Public Title As String End Class Public Sub ReadXML() Dim reader As New System.Xml.Serialization.XmlSerializer(GetType(Book)) Dim file As New System.IO.StreamReader( "c:\temp\SerializationOverview.xml") Dim overview As Book overview = CType(reader.Deserialize(file), Book) Console.WriteLine(overview.Title) End Sub
Replace the file name "c:\IntroToVB.xml" with the name of the file containing the serialized data. For more information about serializing data, see How to: Write Object Data to an XML File (C# and Visual Basic).
The class must have a public constructor without parameters.
Only public properties and fields are deserialized.
The following conditions may cause an exception:
The class being serialized does not have a public, parameterless constructor.
The data in the file does not represent data from the class to be deserialized.
The file does not exist (IOException).
