Ampersand encoding in URL

I have this code in my codebehind...

protected void Page_Init(object sender, EventArgs e)
{
  RegisterCssFile("http://example.com/default.aspx?type=fm&theme=fm");
}

private void RegisterCssFile(string path)
{
  var css = new HtmlGenericControl("link");
  css.Attributes.Add("href", path);
  css.Attributes.Add("type", "text/css");
  css.Attributes.Add("rel", "stylesheet");
  Page.Header.Controls.Add(css);
}

This renders

<link href="http://example.com/default.aspx?type=fm&amp;theme=fm" type="text/css" rel="stylesheet"></link>

... which, as you can see, is wrong.

Why is the ampersand (&) encoded and how can I fix it?

Solution

  • Actually, this is correct. Why do you think it's wrong? It should be sent by the browser as just & after HTML un-escaping. Does something not work for you?
