XmlNodeEventArgs Class
Visual Studio 2010
Provides data for the UnknownNode event.
Assembly: System.Xml (in System.Xml.dll)
The XmlNodeEventArgs type exposes the following members.
| Name | Description | |
|---|---|---|
![]() ![]() | LineNumber | Gets the line number of the unknown XML node. |
![]() ![]() | LinePosition | Gets the position in the line of the unknown XML node. |
![]() ![]() | LocalName | Gets the XML local name of the XML node being deserialized. |
![]() ![]() | Name | Gets the name of the XML node being deserialized. |
![]() ![]() | NamespaceURI | Gets the namespace URI that is associated with the XML node being deserialized. |
![]() ![]() | NodeType | Gets the type of the XML node being deserialized. |
![]() ![]() | ObjectBeingDeserialized | Gets the object being deserialized. |
![]() ![]() | Text | Gets the text of the XML node being deserialized. |
| Name | Description | |
|---|---|---|
![]() ![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() ![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() ![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() ![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() ![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() ![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
For more information about handling events, see Consuming Events.
The UnknownNode event can occur only when you call the Deserialize method.
The following example uses the UnknownNode event of the XmlSerializer to print various properties of an unknown XML node that is encountered when calling the XmlSerializer class's Deserialize method.
#using <System.Xml.dll> #using <System.dll> using namespace System; using namespace System::IO; using namespace System::Xml; using namespace System::Xml::Serialization; public ref class Group { public: // Only the GroupName field will be known. String^ GroupName; }; public ref class Test { public: static void main() { Test^ t = gcnew Test; t->DeserializeObject( "UnknownNodes.xml" ); } private: void DeserializeObject( String^ filename ) { XmlSerializer^ mySerializer = gcnew XmlSerializer( Group::typeid ); FileStream^ fs = gcnew FileStream( filename,FileMode::Open ); mySerializer->UnknownNode += gcnew XmlNodeEventHandler( this, &Test::serializer_UnknownNode ); Group^ myGroup = dynamic_cast<Group^>(mySerializer->Deserialize( fs )); fs->Close(); } private: void serializer_UnknownNode( Object^ /*sender*/, XmlNodeEventArgs^ e ) { Console::WriteLine( "UnknownNode Name: {0}", e->Name ); Console::WriteLine( "UnknownNode LocalName: {0}", e->LocalName ); Console::WriteLine( "UnknownNode Namespace URI: {0}", e->NamespaceURI ); Console::WriteLine( "UnknownNode Text: {0}", e->Text ); XmlNodeType myNodeType = e->NodeType; Console::WriteLine( "NodeType: {0}", myNodeType ); Group^ myGroup = dynamic_cast<Group^>(e->ObjectBeingDeserialized); Console::WriteLine( "GroupName: {0}", myGroup->GroupName ); Console::WriteLine(); } }; int main() { Test::main(); } /* Paste this XML into a file named UnknownNodes: <?xml version="1.0" encoding="utf-8"?> <Group xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:coho = "http://www.cohowinery.com" xmlns:cp="http://www.cpandl.com"> <coho:GroupName>MyGroup</coho:GroupName> <cp:GroupSize>Large</cp:GroupSize> <cp:GroupNumber>444</cp:GroupNumber> <coho:GroupBase>West</coho:GroupBase> <coho:ThingInfo> <Number>1</Number> <Name>Thing1</Name> <Elmo> <Glue>element</Glue> </Elmo> </coho:ThingInfo> </Group> */
