        {
            Regex regx = new Regex("(?=ed2k://)((\\s|.)+?)((?=ed2k://)|$)");
            MatchCollection col= regx.Matches("ed2k://|sadasd213213qwewqe`ed2k://sadasdqwewqe213ewr`ed2k://sadasdqwewqe213ewr");            foreach (Match item in col)
            {
                Console.WriteLine(item.Value);
            }
            Console.WriteLine("end----------------------------------------");
            Console.ReadKey();
