How to tell XmlSerializer to serialize properties with [DefautValue(…)] always?

Question

I am using DefaultValue attribute for the proper PropertyGrid behavior (it shows values different from default in bold). Now if I want to serialize

Answer 1

You could use two properties:

// For property grid only:
[Category(CategoryAnalyse)]
[TypeConverter(typeof(ConverterBoolOnOff))]
[DefaultValue(false)]
[XmlIgnore]
public bool AllowNegative
{
    get { return _allowNegative; }
    set
    {
        _allowNegative = value;
        ConfigBase.OnConfigChanged();
    }
}

// For serialization:
[Browsable(false)]
[EditorBrowsable(EditorBrowsableState.Never)]
[TypeConverter(typeof(ConverterBoolOnOff))]
[XmlElement("AllowNegative")]
public bool AllowNegative_XML
{
    get { return _allowNegative; }
    set
    {
        _allowNegative = value;
        ConfigBase.OnConfigChanged();
    }
}
