字符串的添加与切割~~~

            //把{"诸葛亮"，"鸟叔"，"卡卡西"，"卡哇伊"}变成诸葛亮|鸟叔|卡卡西|卡哇伊，然后再把|切割掉。
              string[] names = { "诸葛亮" ,"鸟叔","卡卡西","卡哇伊"};
              string str = string.Join("|", names);
              string []strNew=str.Split(new char[]{'|'},StringSplitOptions.RemoveEmptyEntries);
              Console.WriteLine(str);
              Console.WriteLine(strNew[0]);
              Console.ReadKey();

            string s = "2008-08-08";
            string[] date = s.Split(new char[] { '-' }, StringSplitOptions.RemoveEmptyEntries);
            Console.WriteLine("{0}年{1}月{2}日", date[0], date[1], date[2]);
            Console.ReadKey();
