I am using the XmlSerializer. It serializes the object just fine but the client requires required empty elements to be in this format <star:Confirm/>. The serializer instead serializes the empty elements to <star:Confirm></star:Confirm> is there a way to change it to serialize the way the client requires.

After trying different things I accidentally happened upon the solution. I set the XmlElementAttribute.IsNullable to true like the previous answer suggested.

[System.Xml.Serialization.XmlElementAttribute(ElementName = "Confirm", IsNullable=true)]
    public ConfirmType Confirm
    {
        get
        {
            return this.confirmField;
        }
        set
        {
            this.confirmField = value;
            this.RaisePropertyChanged("Confirm");
        }
    }

Then when setting the confirm type in the code I used the default constructor instead of setting Confirm to null.

retval.ConfirmBODDataArea.Confirm = new ConfirmType();

This serialized as <star:Confirm/>

  • Thanks for reminding me about default values and that I should be using the default constructor instead of = Nothing in vb.net code! :) – Ian Grainger Nov 02 '16 at 13:49

You can try setting the XmlElementAttribute.IsNullable property to true. However, bear in mind xsi:nil="true" attribute will be output as a consequence.
