Try this: using System; class Test { static void Main() { string[] urls = { @http://g-ecx.images-amazon.com @http://z-ecx.images-amazon.com @http://ecx.images-amazon.com @http://completion.amazon.com @http://client-log.amazon.com @http://www.amazon.com/184-8984226-0489751 @http://www.amazon.com/access @http://www.amazon.com/gp/product/B0083PWAPW/ref=kin_dev_gw_dual_t/184-898422604... @http://www.amazon.com/gp/product/B007OZNZG0/ref=kin_dev_gw_dual_c/184-8984226-04... @http://www.amazon.com/gp/prime/signup/videos/ref=nav_menu_video_redirect_combine... @http://www.amazon.com/gp/prime/signup/videos/ref=nav_menu_video_pic_redirect_com... @http://www.amazon.com/gp/prime/signup/videos/ref=nav_menu_shipping_redirect_comb... @http://www.amazon.com/gp/prime/signup/videos/ref=nav_menu_shipping_pic_redirect_... }; foreach(string url in urls) { Uri uri = new Uri(url); string[] items = uri.Host.Split('.'); string domain = ; if (items.Length == 3) { domain = items[1]; } else if (items.Length == 2) { domain = items[0]; } if (domain.IndexOf('-') > -1) { domain = domain.Substring(domain.LastIndexOf('-') + 1); } Console.WriteLine(domain); } Console.ReadKey(); } }
