我有一个dll,它在我的页面顶部渲染div,我需要删除。是否可以编辑即将呈现的html,以便我可以在显示之前从html中删除div:
protected override void Render(HtmlTextWriter writer)
{
// setup a TextWriter to capture the markup
TextWriter tw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(tw);
// render the markup into our surrogate TextWriter
base.Render(htw);
// get the captured markup as a string
string pageSource = tw.ToString();
// render the markup into the output stream verbatim
writer.Write(pageSource);
// remove the viewstate field from the captured markup
//string viewStateRemoved = Regex.Replace(pageSource,
// "<input type=\"hidden\" name=\"__VIEWSTATE\" id=\"__VIEWSTATE\" value=\".*?\" />",
// "", RegexOptions.IgnoreCase);
// the page source, without the viewstate field, is in viewStateRemoved
// do what you like with it
}
