The following C# implementation will serialize a .NET Framework class into an XML string.

using System;
using System.Xml;
using System.Xml.Serialization;
using System.IO;
using System.Globalization;

/// <summary>
/// This method wraps an XmlSerializer and turns a presence data class 
/// object into its corresponding XML string.
/// </summary>
/// <param name="objectToSerialize">
/// A presence data class object to be serialized into the string
/// representation of an XML element according to the definition of
/// the type specified in the second parameter of this method. 
/// </param>
/// <param name="type">The type of object to serialize. Depending 
/// on the XML Schema definition, this may have to be a super type 
/// of the object specified in the first parameter</param>
/// <returns>An XML string of the specified presence data</returns>
public static String Serialize(Object objectToSerialize, Type type)
{
     if (objectToSerialize == null) 
        throw new ArgumentNullException("objectToSerialize");
     if (type == null) 
        throw new ArgumentNullException("type");

     XmlSerializer serializer = new XmlSerializer(type);
     StringWriter sw = new StringWriter(new StringBuilder(128), 
                                 CultureInfo.InvariantCulture);
     XmlWriterSettings setting = new XmlWriterSettings();
     setting.OmitXmlDeclaration = true;
     setting.Indent = true;
     setting.IndentChars = "   ";
     setting.NewLineOnAttributes = true;
     XmlWriter messageWriter = XmlWriter.Create(sw, setting);
     serializer.Serialize(messageWriter, objectToSerialize);
     messageWriter.Close();
     sw.Close();

     return sw.ToString();
}
