確實是畫蛇添足，看我寫的
static void Main(string[] args) { Action<string> messageTarget; if (Environment.GetCommandLineArgs().Length > 1) //messageTarget = ShowWindowsMessage;//第一種，用定義的方法名 messageTarget = (x) => Console.WriteLine("匿名委托" + x);//第二種 else messageTarget = delegate(string s) { Console.WriteLine(s); }; messageTarget("Hello, World!"); Console.ReadLine(); } private static void ShowWindowsMessage(string message) { Console.WriteLine("最好加上標識以區別于參數為0" + message); } |
