在cs页取得当前Web页输出的HTML

这几天遇到个问题，要在CS页里取得当前输出的HTML，试了试，这个方法不错，写出来，不知道大家有没有更好的方法？

System.Globalization.CultureInfo Culture = new System.Globalization.CultureInfo("ZH-CN",true);

System.IO.StringWriter Writer = new System.IO.StringWriter(Culture);

System.Web.UI.HtmlTextWriter HtmlWriter = new System.Web.UI.HtmlTextWriter(Writer);

this.Page.RenderControl(HtmlWriter);

string Html = Writer.ToString();
