Generates an object from its XML representation.
Assembly: System.Xml (in System.Xml.dll)
Sub ReadXml ( _
reader As XmlReader _
)void ReadXml(
XmlReader reader
)void ReadXml(
XmlReader^ reader
)abstract ReadXml :
reader:XmlReader -> unit
Parameters
- reader
- Type: System.Xml
. . :: . XmlReader
The XmlReader stream from which the object is deserialized.
The ReadXml method must reconstitute your object using the information that was written by the WriteXml method.
When this method is called, the reader is positioned at the start of the element that wraps the information for your type. That is, just before the start tag that indicates the beginning of a serialized object. When this method returns, it must have read the entire element from beginning to end, including all of its contents. Unlike the WriteXml method, the framework does not handle the wrapper element automatically. Your implementation must do so. Failing to observe these positioning rules may cause code to generate unexpected runtime exceptions or corrupt data.
When implementing this method, you should consider the possibility that a malicious user might provide a well-formed but invalid XML representation in order to disable or otherwise alter the behavior of your application.
The following example illustrates an implementation of the ReadXml method.
Public Sub ReadXml(ByVal reader As XmlReader) Implements IXmlSerializable.ReadXml
personName = reader.ReadString()
End Sub
public void ReadXml (XmlReader reader)
{
personName = reader.ReadString();
}
virtual void ReadXml( XmlReader^ reader )
{
personName = reader->ReadString();
}
The following example illustrates the use of the XmlSerializer class to deserialize this object.
Imports System
Imports System.IO
Imports System.Xml.Serialization
Public Class Reader
Public Shared Sub Main()
Dim serializer As New XmlSerializer(GetType(Person))
Dim file As New FileStream("test.xml", FileMode.Open)
Dim aPerson As Person = CType(serializer.Deserialize(file), Person)
Console.WriteLine(aPerson)
End Sub
End Class
using System;
using System.IO;
using System.Xml.Serialization;
public class Reader {
public static void Main() {
XmlSerializer serializer = new XmlSerializer(typeof(Person));
FileStream file = new FileStream("test.xml", FileMode.Open);
Person aPerson = (Person) serializer.Deserialize(file);
Console.WriteLine(aPerson);
}
}
#using <System.Xml.dll>
#using <System.dll>
#using <Person.dll>
using namespace System;
using namespace System::IO;
using namespace System::Xml::Serialization;
int main()
{
XmlSerializer^ serializer = gcnew XmlSerializer( Person::typeid );
FileStream^ file = gcnew FileStream( "test.xml",FileMode::Open );
Person^ aPerson = dynamic_cast<Person^>(serializer->Deserialize( file ));
Console::WriteLine( aPerson );
}
