IXmlSerializable.ReadXml Method
Assembly: System.Xml (in system.xml.dll)
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 void ReadXml(XmlReader reader)
{
personName = reader.ReadString();
} //ReadXml
The following example illustrates the use of the XmlSerializer class to deserialize this object.
#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 ); }
