! An end tag cannot be added for an empty XML Node during serialization.

To use XmlSerializer to serialize an object, it is required that the empty node be expressed as the start and end marking pairs:

Current format: <Wards/>

Expected format: <Wards> </Wards>

I searched for it online. C #-XmlSerializer Serialize empty variable to use both tags? The solution is:

Public class XmlTextWriterFull: XmlTextWriter {
Public XmlTextWriterFull (Stream stream, Encoding enc): base (stream, enc ){}
Public XmlTextWriterFull (String str, Encoding enc): base (str, enc ){}
Public XmlTextWriterFull (TextWriter sink): base (sink ){}

Public override void WriteEndElement (){
Base. WriteFullEndElement ();
}
}

 

Then I call:

MemoryStream stream = new MemoryStream ();
XmlSerializer serializer = new XmlSerializer (message. GetType ());
XmlTextWriter writer = new XmlTextWriterFull (stream, Encoding. Unicode );

Serializer. Serialize (writer, message );
StreamReader reader = new StreamReader (stream, Encoding. Unicode );
Stream. Position = 0;
String xml = reader. ReadToEnd ();
Stream. Close ();
Writer. Close ();
Reader. Close ();

 

Unfortunately, it never succeeds.
