程式碼之間的區別

委託

        delegate int calculator(int x, int y); //定義委託
        static void Main()
        {
            calculator cal = new calculator(Adding);
            int He = cal(1, 1);
            Console.Write(He);
        }
       
        // 加法        
        public static int Adding(int x, int y)
        {
            return x + y;
        }
 

匿名方法

        delegate int calculator(int x, int y); //定義委託
        static void Main()
        {
            calculator cal = delegate(int num1,int num2)
            {
                return num1 + num2;
            };
            int he = cal(1, 1);
            Console.Write(he);
        }

Lambda表示式

        delegate int calculator(int x, int y); //定義委託
        static void Main()
        {
            calculator cal = (x, y) => x + y;//Lambda表示式，很簡潔，Linq類似
            int he = cal(1, 1);
            Console.Write(he);
        }
 

Func<T>委託

static void Main(string[] args)
        {
            Func<int, int, bool> gwl = (p, j) =>
                {
                    if (p + j == 10)
                    {
                        return true;
                    }
                    return false;
                };
            Console.WriteLine(gwl(5,5) + "");   //列印‘True’，z對應引數b，p對應引數a
            Console.ReadKey();
        }
