正则替换的问题，顺便放分
http://www.myurl.com/abcd.html
或者
www.myurl.com/abcd.html

替换为
http://www.myurl.com/SSS.aspx?id=abcd

使用正则替换；

[解决办法]

C# code

string s = "http://www.myurl.com/abcd.html";            System.Text.RegularExpressions.Regex regex = new System.Text.RegularExpressions.Regex("http://www.myurl.com/(.*?).html");            System.Text.RegularExpressions.MatchCollection matches = regex.Matches(s);            s = string.Format("http://www.myurl.com/SSS.aspx?id={0}", matches[0].Groups[1]);            Console.WriteLine(s);
[解决办法]
string reg= "(http://)?www.myurl.com/([^.]+).html";
string ObjectStr = Regex.Replace("http://www.myurl.com/abcd.html", reg,"http://www.myurl.com/SSS.aspx?id=$2",);
Response.Write(ObjectStr);

VB.NET code
Imports System.Text.RegularExpressionsModule Module1    Sub Main()        Dim str = "www.myurl.com/abcd.html"        Console.WriteLine(GetHtml(str))    End Sub    Function GetHtml(ByVal input As String) As String        Return Regex.Replace(input, "(.+)/([^.]+)\.(html)", "$1/" & "SSS" & ".aspx?id=" & "$2")    End FunctionEnd Module
