C# 委托/Func() 中 GetInvocationList() 方法的使用 | 接收委托多个返回值

  class Program
    {
        public static string a(string str)
        {
            Console.WriteLine("方法a");
            return str+"方法a";
        }
        public static string b(string str)
        {
            Console.WriteLine("方法b");
            return str + "方法b";
        }
        public static string c(string str)
        {
            Console.WriteLine("方法c");
            return str + "方法c";
        }
        static void Main(string[] args)
        {
            Funcstring, string> func=a;
            func += b;
            func += c;
            Console.WriteLine(func("测试"));
            Console.ReadKey();
        }

    }

    class Program
    {
        public static string a(string str)
        {
            Console.WriteLine("方法a");
            return str+"方法a";
        }
        public static string b(string str)
