    {
        static void Main()
        {
            ConvertMethod ConvertUpperstring = upperCaseString;
            Console.WriteLine("Using delegate instance to call upperString method");
            Console.WriteLine(ConvertUpperstring("guohu"));
            Console.WriteLine("--------------------");
            Console.WriteLine("Using anonymous delegate");
            ConvertMethod ConvertAsynCaseString = delegate(string s)
            {

            };
            Console.WriteLine(ConvertAsynCaseString("leihu"));
            Console.WriteLine("--------------------");
            Console.WriteLine("Using Func<int T,Out TResult>");
            Func<string, string> FuncCaseUpper = upperCaseString;
            Console.WriteLine(FuncCaseUpper("junwenLi"));
            Console.WriteLine("--------------------");
            Console.WriteLine("Using anonymous Func<int T,Out TResult>");
