Hi, I am begginer and I have one problem. I read tutorial about  Customizing XML Serialization with IXmlSerializable from

http://www.c-sharpcorner.com/UploadFile/prvn_131971/WebServiceStandardsandExtensions02072008073635AM/WebServiceStandardsandExtensions.aspx

Class which is serialize :

public class EmployeeDetailsCustom : IXmlSerializable

{

    public int ID;

    public string FirstName;

    public string LastName;

    const string ns = "http://www.apress.com/ProASP.NET/CustomEmployeeDetails";

    void IXmlSerializable.WriteXml(XmlWriter w)

    {

        w.WriteStartElement("Employee", ns);

        w.WriteStartElement("Name", ns);

        w.WriteElementString("First", ns, FirstName);

        w.WriteElementString("Last", ns, LastName);

        w.WriteEndElement();

        w.WriteElementString("ID", ns, ID.ToString());

        w.WriteEndElement();

    }

    void IXmlSerializable.ReadXml(XmlReader r)

    {

        r.MoveToContent();

        r.ReadStartElement("Employee");

        r.ReadStartElement("Name");

        FirstName = r.ReadElementString("First", ns);

        LastName = r.ReadElementString("Last", ns);

        r.ReadEndElement();

        r.MoveToContent();

        ID = Int32.Parse(r.ReadElementString("ID", ns));

        reader.ReadEndElement();

    }

    System.Xml.Schema.XmlSchema IXmlSerializable.GetSchema()

    {

        return null;

    }

    // (Constructors omitted.)

}

Method which return XML scheme as XmlQualifiedName object .

public static XmlQualifiedName GetSchemaDocument(XmlSchemaSet xs)

{

   // Get the path to the schema file.

   string schemaPath = HttpContext.Current.Server.MapPath("EmployeeDetails.xsd");

   // Retrieve the schema from the file.

   XmlSerializer schemaSerializer = new XmlSerializer(typeof(XmlSchema));

   XmlSchema s = (XmlSchema)schemaSerializer.Deserialize(new XmlTextReader(schemaPath), null);

   xs.XmlResolver = new XmlUrlResolver();

   xs.Add(s);

   return new XmlQualifiedName("EmployeeDetails", ns);

}

Implementation on web method.

[XmlSchemaProvider("GetSchemaDocument")]

public class EmployeeDetailsCustom : IXmlSerializable

{ ... }

The method  public static XmlQualifiedName GetSchemaDocument load xml scheme from file. My question is how can I get xml scheme from my own object. It must be wrote be me , or can be generated with some utility or object from .NET ?

What is the simple way how get xml scheme from my own object. Thank..
