I need to replicate this XML structure with class instances but I am failing on the xmlAttribute xsi:type="array"
This is my plain class setup, I tried a hundred things from various posts and tutorials like XmlInclude but i can't seem to make it work:
private ST_DtxInstance dtxFile = new ST_DtxInstance();
[System.Xml.Serialization.XmlRootAttribute(ElementName = "Database", Namespace = "http://www.staubli.com/robotics/VAL3/Data/2", IsNullable = false)]
public class ST_DtxInstance
{
[XmlArray("Datas")]
[XmlArrayItem("Data")]
public ST_Data[] csDatas = new ST_Data[] { new ST_Data(), new ST_Data() };
}
public class ST_Data
{
[XmlElement("Value")]
public ST_Value value = new ST_Value();
[XmlAttribute("name")]
public string csName = "Name";
[XmlAttribute("access")]
public string csAccess = "public";
[XmlAttribute(AttributeName = "type", Namespace = "http://www.w3.org/2001/XMLSchema-instance")]
public string xsi_xmlType = "array";
[XmlAttribute("type")]
public string csType = "NA";
[XmlAttribute("size")]
public string csSize = "-1";
}
public class ST_Field
{
[XmlElement("Value")]
public ST_Value csValue = new ST_Value();
[XmlAttribute("name")]
public string csName = "Name of Type";
[XmlAttribute(AttributeName = "type", Namespace = "http://www.w3.org/2001/XMLSchema-instance")]
public string xsi_xmlType = "array"; //always array
[XmlAttribute("type")]
public string csType = "NA";
[XmlAttribute("size")]
public string csSize = "1";
}
public class ST_Value
{
[XmlArrayItem(ElementName = "Field")]
public ST_Field[] csDatas = null;
[XmlAttribute(AttributeName = "key")]
public int csKey = -1;
[XmlAttribute(AttributeName = "link")]
public string csLink = "NA";
}
private ST_DtxInstance DeserializeDTX(string xmlPath)
{
DisplayFile(xmlPath);
XmlSerializer serializer = new XmlSerializer(typeof(ST_DtxInstance));
var fileReader = new FileStream(xmlPath, FileMode.Open);
var result = (ST_DtxInstance)serializer.Deserialize(fileReader);
fileReader.Close();
return result;
}
private void SerializeDTX(ST_DtxInstance instance, string xmlPath)
{
XmlSerializer serializer = new XmlSerializer(typeof(ST_DtxInstance));
TextWriter fileWriter = new StreamWriter(xmlPath);
XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
ns.Add("xsi", "http://www.w3.org/2001/XMLSchema-instance");
serializer.Serialize(fileWriter, instance, ns);
fileWriter.Close();
DisplayFile(xmlPath);
}
private void DisplayFile(string path)
{
labl.Content = File.ReadAllText(path);
}
And this is the XML-format want to read and write

<Field name="SpeedLimit" xsi:type="array" type="num" size="1" />
</Value>
</Field>
</Value>
</Data>
</Datas>
</Database>
Also, occasionally there might also be an xsi:type="collection" instead of an "array" on some elements within the same array.

I got it working by serializing data and getting serialize output to match input
