我在网上查了这么个代码，可是下面的这句看不懂哈，各位师哥师姐能讲下否？
             // string[] strArr = Array.ConvertAll<char, string>(chr, delegate(Char c) { return c.ToString(); });
代码为：      
            string str;
            Console.WriteLine("Enter a string:");
            str=Console.ReadLine();
            char[] chr = str.ToCharArray();
            Array.Reverse(chr);
            string[] strArr = Array.ConvertAll<char, string>(chr, delegate(Char c) { return c.ToString(); });
            str = string.Join("", strArr);
            Console.WriteLine(str);
