Serialize/Deserialize Variant Value in XML

[UA_Developer]

Hello,

i have a problem concerning the serialization of a UA model on my OPC UA server. I want to store my transferred datatype in an xml document.

Using XMLSerializer:

Code: Select all

xs = new XmlSerializer(typeof(CustomDataType));
XmlDocument xmlDocument = new XmlDocument();

using (var fs = new FileStream(path, FileMode.OpenOrCreate))
{
	using (tw = new StreamWriter(fs))
	{
		xs.Serialize(tw, jobOrder);
	}
}

My CustomDataType contains beside common data types like string, etc. also a DataMember of type Variant.

Code: Select all

        [DataMember(Name = "Value", IsRequired = false, Order = 2)]
        public Variant Value
        {
            get
            {
                return m_Value;
            }
            set
            {
                m_Value = value;
            }
        }

During serialization, the data for the type Variant is apparently not considered and not written into the XML document.

Does anyone have an idea how I can serialize this data and write it there?

Thanks for the help-
