Question

I’m trying to serialize a xml file into a class where a element can be empty

XML file

  <Status StatusId="1">
    <StatusName>Not inspected</StatusName>
    <Acute></Acute>
  </Status>
  <Status StatusId="2">
    <StatusName>Acute</StatusName>
    <Acute>1</Acute>
  </Status>

The class

 private int _acute;
         public int Acute
         {
             get { return _acute; }
             set
             {       
                   _acute = value;
                    NotifyPropertyChanged("Acute");

             }
         }

I have tried int? and [XmlElement( IsNullable = true )] but nothing works anyone know how to read in empty elemet without getting any errors.

Answer 1

Try making Acute an int? . Ints can’t contain null, nullable ints (int?s) can.

EDIT: Note to self – read everything before responding.

Perhaps your problem is that <Acute> isn’t actually missing from the XML, it’s there but with an empty value, which doesn’t translate to any int? Try removing the <Acute></Acute> line from the XML, and change the property back to int? .
