c#: escape XML string and write to HTML

I am reading an XML file and I want to write the actual contents to HTML. I think the problem is that HtmlTextWriter is treating my XML tags as HTML tags. I have tried using HttpUtility.HtmlEncode/Decode and SecurityElement.Escape but these don't work. How do I escape the tags so that I get literal strings to write to my HTML page.

private string WriteXmlToHtml()
    {
        StringWriter stringWriter = new StringWriter();

        using (HtmlTextWriter writer = new HtmlTextWriter(stringWriter))
        {
            int counter = 0;
            string line;

            StreamReader file = new StreamReader("test.xml");

            while ((line = file.ReadLine()) != null)
            {
                //HttpUtility.HtmlDecode(line);
                //System.Security.SecurityElement.Escape
                writer.Write(line);
                counter++;
            }
        }

        return stringWriter.ToString();
    }

//edit: I have shamelessy implemented Xanatos' <pre> tags into the output string. Source in the comments

writer.Write(String.Format("<pre>{0}</pre>",HttpUtility.HtmlEncode(line)));

produces the following output:

<?xml version="1.0" encoding="utf-8"?>
<Settings>
 <Code>D:picture\simple</Code>
...

plus it adds a line break after each line. Unfortunately it does not keep the indention.

This should get rendered as valid xml in your html file.

Try using this:

private string WriteXmlToHtml()
{
    string filePath = @"d:\abc.xml";
    return Server.HtmlEncode(File.ReadAllText(filePath));
}
