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);     

} 

}

asp.net页面过滤所有换行符和多余空格
