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。

using System; 
using System.Data; 
using System.Configuration; 
using System.Web;
using System.Web.Security; 
using System.Web.UI; 
using System.Web.UI.WebControls; 
using System.Web.UI.HtmlControls;
using System.Text.RegularExpressions; 
using System.IO;  
/// <summary> 
/// PageBase 页面基类
/// </summary> 
public class PageBase : System.Web.UI.Page 
{     
 protected override void Render(HtmlTextWriter writer)     
 {        
  StringWriter sw = new StringWriter();         
  HtmlTextWriter htmlWriter = new HtmlTextWriter(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);     
 } 
}
