Answer 1

 string s=@"C:\Users***\Perforce\EASAP\jiawang_EASHDPDESK257_6678\nucleus\SANDBOX\henryzhu\ProductAPIValidator\ProductAPIValidator\bin\Debug\log_error.log";
string []arr=s.Split('\\');//arr[arr.Length-1]就是

正则用这个

         Regex r = new Regex(@"\\([^\\]+)$");
        string s = @"C:\Users***\Perforce\EASAP\jiawang_EASHDPDESK257_6678\nucleus\SANDBOX\henryzhu\ProductAPIValidator\ProductAPIValidator\bin\Debug\log_error.log";
        Match match = r.Match(s);
        Response.Write(match.Groups[1].Value);
        Response.End();
