Question

I have this xml file :

<?xml version="1.0" encoding="us-ascii"?>
<body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <header><user>BOBBY</user></header>
    <in>
        <customer>0123456789</customer>
    </in>
    <out>
        <cmd>
            <productid></productid>
            <price></price>
            <date></date>
            <state></state>
            <type></type>
        </cmd>
        <cmd>
            <productid></productid>
            <price></price>
            <date></date>
            <state></state>
            <type></type>
        </cmd>
    </out>
    <state>
        <code></code>
        <desc></desc>
    </state>
</body>

And Xsd.Exe generate this class :

namespace System.autoGenerated {
    using System.Xml.Serialization;

How can i use this file? I don't understand how to use it in an extend class for use this partial class.

My goal is to serialie and deserialize and object. ----------------------------------UPDATE----------------------------

I've already create this testing code : using System; using DAL.XML.PDD.PDDORDM001; using System.Xml.Serialization; using System.IO;

namespace Tests
{
    class Serialize
    {
        public static void Main()
        {
            Console.WriteLine("Go...");

            XmlSerializer serializer = new XmlSerializer(typeof(body));
            TextWriter writer = new StreamWriter(@"c:\file.xml");
            body test = null;
            serializer.Serialize(writer, test);
            writer.Close();

        }
    }
}

But it give me this result :

<?xml version="1.0" encoding="utf-8"?>
<body xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" />
Was it helpful?

Solution

You need to use XmlSerializer to serialize object and deserialize xml:

using (var stream = new FileStream(xmlFilePath))
{
     var serializer = new XmlSerializer(typeof(body));
     var body = (body) serializer.Deserialize(stream);
 }

OTHER TIPS

Solution : I have modify the Xml class :

    [System.Xml.Serialization.XmlElementAttribute("Header", typeof(BodyHeader), Form=System.Xml.Schema.XmlSchemaForm.Unqualified)]
    [System.Xml.Serialization.XmlElementAttribute("In", typeof(BodyIn), Form=System.Xml.Schema.XmlSchemaForm.Unqualified)]
    [System.Xml.Serialization.XmlElementAttribute("State", typeof(BodyState), Form=System.Xml.Schema.XmlSchemaForm.Unqualified)]
    [System.Xml.Serialization.XmlElementAttribute("Out", typeof(BodyOut), Form=System.Xml.Schema.XmlSchemaForm.Unqualified)]
    public object[] Items;

replace by 

    [System.Xml.Serialization.XmlElementAttribute("Header", typeof(BodyHeader), Form = System.Xml.Schema.XmlSchemaForm.Unqualified)]
    public BodyHeader header;

    [System.Xml.Serialization.XmlElementAttribute("In", typeof(BodyIn), Form=System.Xml.Schema.XmlSchemaForm.Unqualified)]
    public In in;

    [System.Xml.Serialization.XmlElementAttribute("State", typeof(BodyState), Form=System.Xml.Schema.XmlSchemaForm.Unqualified)]
    public BodyState state;

    [System.Xml.Serialization.XmlElementAttribute("Out", typeof(BodyOut), Form=System.Xml.Schema.XmlSchemaForm.Unqualified)]
    public BodyOut out;

And my testing code :

using System;
using DAL.XML.PDD.PDDORDM001;
using System.Xml.Serialization;
using System.IO;

namespace Tests
{
    class Serialize
    {
        public static void Main()
        {
            Console.WriteLine("Serialisation...");


            XmlSerializer serializer = new XmlSerializer(typeof(DAL.XML.PDD.PDDORDM001.Body));
            TextWriter writer = new StreamWriter(@"c:\file.xml");
            DAL.XML.PDD.PDDORDM001.Bodytest = new DAL.XML.PDD.PDDORDM001.Body();

            test.header= new BodyHeader();
            test.header.action = "LEC";
            test.header.user = "BOBBY";

            test.in= new BodyIn();
            test.in.customer= "07251005502";

            serializer.Serialize(writer, test);
            writer.Close();

        }
    }
}

You probably want to use the DataContractSerializer class. Here's an example from its documentation, modified slightly to fit your usage:

public static body ReadObject(string fileName)
{
    Console.WriteLine("Deserializing an instance of the object.");
    FileStream fs = new FileStream(fileName,
    FileMode.Open);
    XmlDictionaryReader reader =
       XmlDictionaryReader.CreateTextReader(fs, new XmlDictionaryReaderQuotas());
    DataContractSerializer ser = new DataContractSerializer(typeof(body));

    // Deserialize the data and read it from the instance.
    body deserializedBody = (body)ser.ReadObject(reader, true);
    reader.Close();
    fs.Close();
    return deserializedBody;
}

Another option is the XmlSerializer class.
