求一替换正则表达式

macpc 2009-10-27 01:24:53



string url = @"<a disabled=""disabled"" style=""margin-right:5px;"">首页</a><a disabled=""disabled"" style=""margin-right:5px;"">上一页</a><span class=""cpb"" style=""margin-right:5px;"">1</span><a href=""WriteAndUpByftp.aspx?page=2"" class=""paginator"" style=""margin-right:5px;"">2</a><a href=""WriteAndUpByftp.aspx?page=3"" class=""paginator"" style=""margin-right:5px;"">3</a><a class=""paginator"" href=""WriteAndUpByftp.aspx?page=2"" style=""margin-right:5px;"">下一页</a><a class=""paginator"" href=""WriteAndUpByftp.aspx?page=3"" style=""margin-right:5px;"">尾页</a>

";

        string pattern = @"";//正则我应怎样写？

        Regex rgx = new Regex(pattern);

        string a = rgx.Replace(url,"");//这里怎么写？

        Response.Write(a);

我需要将所有WriteAndUpByftp.aspx?page=1 WriteAndUpByftp.aspx?page=2……等WriteAndUpByftp.aspx?page开头的替换成如aabb1.htm aabb2.htm……这样的语名，再比如：
WriteAndUpByftp.aspx?page=1 ——aabb1.htm
WriteAndUpByftp.aspx?page=2——aabb2.htm
WriteAndUpByftp.aspx?page=3——aabb3.htm

string oldUrl = HttpContext.Current.Request.RawUrl;

string pattern = @"^(.+)News(d+).html(?.*)*$";

　　string replace = "$1NewsDetails.aspx?NID=$2";

if (Regex.IsMatch(oldUrl, pattern, RegexOptions.IgnoreCase | RegexOptions.Compiled))

　　{

　　　　string newUrl = Regex.Replace(oldUrl, pattern, replace,

　　　　　　RegexOptions.Compiled | RegexOptions.IgnoreCase);

　　　　this.Context.RewritePath(newUrl);

　　}
