class Program
    {
        public delegate string trans(string s);
        static void Main(string[] args)
        {                                
            string s = "abcdEFGH"; 
            trans tran = (string str) => { return str.Substring(0, 1).ToUpper() + str.Substring(1).ToLower(); };
            Console.WriteLine(tran(s));
            Console.Read();
