asp.net页面过滤所有换行符和多余空格

不知道大家注意到了没有，Google和Baidu网页的HTML源代码是混合在一起的。HTML代码混合在一起，出发点是为了减小网页体积，从而加快网页加载速度。

      写个函数把网页HTML源代码的换行符和空格过滤掉其实并不难，我这里是写了个基类，在asp.net编程时，页面只要继承这个基类，那么输出的HTML代码就会自动去掉换行符，和多余的空格符号，例如“> <”之间的空格符号。

StringWriter sw =newStringWriter();
HtmlTextWriter htmlWriter =newHtmlTextWriter(sw);
base.Render(htmlWriter);
string html = sw.ToString();
html =Regex.Replace(html,"[f v]","");
html =Regex.Replace(html," {2,}"," ");
html =Regex.Replace(html,">[ ]{1}",">");
writer.Write(html);
}
}
