函数指针delegate

行内人一看这标题就会笑着说“小样，delegate不止是函数指针”。但是如果你像我一样，只是想把delegate当做函数指针用，那么这篇文章正是你要找的。例子一目了然。

class CC
    {
        private int id;
        public static string getClassName()
        {
            return "CC";
        }
        public CC(int id)
        {
            this.id = id;
        }
        public int increaseID(int inc)
        {
            this.id += inc;
            return this.id;
        }
    }

class Program
    {
        public delegate string DgetClassName();
        public delegate int DincreaseID(int inc);
        static void Main(string[] args)
        {
            CC cc = new CC(1);
            DgetClassName getName = (DgetClassName)Delegate.CreateDelegate(typeof(DgetClassName), typeof(CC), "getClassName");
            DincreaseID increaseID = (DincreaseID)Delegate.CreateDelegate(typeof(DincreaseID), cc, "increaseID");
            Console.WriteLine(getName()); // output: CC
            Console.WriteLine(increaseID(50)); // output: 51
            Console.Read();
        }
    }
