    class TestDelegate
    {
        public delegate void DelegateMethod(); //声明了一个Delegate Type

public DelegateMethod delegateMethod; //声明了一个Delegate对象

        public static void StaticMethod()
        {
            Console.WriteLine("Delegate a static method");
        }

        public void NonStaticMethod()

            if (delegateMethod != null)
            {
