Writing a <meta> tag using HTMLTextWriter in C# issue

I'm trying to render a basic HTML webpage using C# and HTMLTextWriter to output to a WebBrower object, but am having issues rendering the <meta> tag in my HTML output.

What I am expecting to be output..

<!DOCTYPE html>
<html>

  <head>
    <meta charset="UTF-8">
    <title>My Website</title>
  </head>

  <body>
    <h1>Hello World!</h1>
  </body>

</html>

What is currently being output..

<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8">
    </meta charset="UTF-8"><title>
      My Website
    </title>
    </head><body>
    <h1>
      Hello World!
    </h1>
  </body>
</html>

Notice how the <meta> tag is being output as <meta charset="UTF-8"> & </meta charset="UTF-8"> instead of just <meta charset="UTF-8">.

What can I do to correct this issue?

Here is the code I am using..

var sw = new StringWriter();
using (var writer = new HtmlTextWriter(sw)) {
    writer.RenderBeginTag("!DOCTYPE html");
    writer.RenderBeginTag(HtmlTextWriterTag.Html);
        writer.RenderBeginTag(HtmlTextWriterTag.Head);
            writer.RenderBeginTag("meta charset=\"UTF-8\"");
            writer.RenderEndTag();
            writer.RenderBeginTag(HtmlTextWriterTag.Title);
                writer.Write("SIT323 - My Website");
            writer.RenderEndTag();
        writer.RenderEndTag();
        writer.RenderBeginTag(HtmlTextWriterTag.Body);
            writer.RenderBeginTag(HtmlTextWriterTag.H1);
                writer.Write("Hello World!");
            writer.RenderEndTag();
        writer.RenderEndTag();
    writer.RenderEndTag();
};
return sw.ToString();

Solution

Try it:

writer.AddAttribute("charset", "UTF-8");
writer.RenderBeginTag(HtmlTextWriterTag.Meta);
// Other needed methods...
writer.RenderEndTag();

Result:

<meta charset="UTF-8">

The coding pattern for rendering markup elements is as follows:

Use the AddAttribute method to add any attributes to the element.
Use the RenderBeginTag method.
Use other methods as needed to render the content found between the element's opening and closing tags.
Use the RenderEndTag method.
