asp.net页面过滤所有换行符和多余空格

mac2022-06-30 16

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。

usingSystem; usingSystem.Data; usingSystem.Configuration; usingSystem.Web; usingSystem.Web.Security; usingSystem.Web.UI; usingSystem.Web.UI.WebControls; usingSystem.Web.UI.HtmlControls; usingSystem.Text.RegularExpressions; usingSystem.IO; /// <summary> /// PageBase 页面基类 /// </summary> publicclassPageBase:System.Web.UI.Page{ protectedoverridevoidRender(HtmlTextWriter writer) { StringWriter sw =newStringWriter(); HtmlTextWriter htmlWriter =newHtmlTextWriter(sw); base.Render(htmlWriter); string html = sw.ToString(); html =Regex.Replace(html,"[\f\n\r\t\v]",""); html =Regex.Replace(html," {2,}"," "); html =Regex.Replace(html,">[ ]{1}",">"); writer.Write(html); } }
