C#正则表达式 匹配磁盘路径和文件名

正则表达式相关知识，参考MSDN文档：http://msdn.microsoft.com/zh-cn/library/az24scfc.aspx 和 http://msdn.microsoft.com/zh-cn/library/63ew9az0.aspx

class Program{    static void Main(string[] args)    {        Regex reg = new Regex(@"^(?<fpath>([a-zA-Z]:\\)([\s\.\-\w]+\\)*)(?<fname>[\w]+.[\w]+)");        Match result = reg.Match(@"D:\Program Files\AliWangWang\7.10.07C\emotions\TaoDoll\Sniffer.dat");        if (result.Success)        {            Console.WriteLine("[Full]:" + result.Value);            Console.WriteLine("[Part1]:" + result.Result("${fpath}"));            Console.WriteLine("[Part2]:" + result.Result("${fname}"));        }        Console.ReadLine();    }} 

简单整理如下，方便以后调用(支持多后缀名)：
