Show an object instance as an xnl on your page

This sample code demonstrates how to show an instance of an object in XML format on a page. It encodes the xml serialized string and dumps it as a code into a placeholder.

    public void ShowXmlObject<T>( T instance)

    {

        var ms = new MemoryStream();

        System.Xml.XmlTextWriter writer = new System.Xml.XmlTextWriter(ms, Encoding.Unicode);

        var serializer = new System.Xml.Serialization.XmlSerializer(typeof(T));

        serializer.Serialize(writer, instance);

        writer.Flush();

        ms.Position = 0;

        var reader = new StreamReader(ms);

        LogCode(HttpUtility.HtmlEncode(IndentXml(reader.ReadToEnd())));

    }

    public string IndentXml(string xml)

    {

        var p = xml.LastIndexOf("?>");

        if (p > 0)

            xml = xml.Substring(p + 2);

        var doc = new System.Xml.XmlDocument();

        doc.LoadXml(xml);

        var settings = new System.Xml.XmlWriterSettings();

        settings.Indent = true;

        settings.IndentChars = "  ";

        settings.NewLineChars = "\r\n";

        settings.NewLineHandling = System.Xml.NewLineHandling.None;

        var  sbOutput = new StringBuilder();

        var writer = System.Xml.XmlWriter.Create(sbOutput, settings);

        doc.Save(writer);

        writer.Close();

        return sbOutput.ToString();

    } 

    public void LogCode(string message)

    {

        placeResult.Controls.Add(new Literal() { Text = "<pre><code>" + message + "</code></pre>" });

    }
