WCF中的LoadControl

由于我无法从WCF服务访问TemplateControl或页面,我想知道是否可以呈现自定义控件?如果有的话,怎么办?

 private string GetRenderedHtmlFrom(Control control)
 {
        StringBuilder stringBuilder = new StringBuilder();
        StringWriter sw = new System.IO.StringWriter(stringBuilder);
        HtmlTextWriter htmlWriter  = new HtmlTextWriter(textWriter);
        control.RenderControl(htmlWriter );
        return stringBuilder.ToString();
 }

谢谢
