你好，messageTarget不就是委托吗？还这样写delegate(string s) {？

Question

public class TestAnonMethod{public static void Main(){Action<string> messageTarget;if (Environment.GetCommandLineArgs().Length > 1)messageTarget = delegate(string s) { ShowWindowsMessage(s); };elsemessageTarget = delegate(string s) { Console.WriteLine(s); };messageTarget("Hello, World!");}private static void ShowWindowsMessage(string message){MessageBox.Show(message);}}

确实是画蛇添足，看我写的

static void Main(string[] args)        {            Action<string> messageTarget;             if (Environment.GetCommandLineArgs().Length > 1)                //messageTarget = ShowWindowsMessage;//第一种，用定义的方法名                messageTarget = (x) => Console.WriteLine("匿名委托" + x);//第二种            else                messageTarget = delegate(string s) { Console.WriteLine(s); };             messageTarget("Hello, World!");             Console.ReadLine();        }         private static void ShowWindowsMessage(string message)        {            Console.WriteLine("最好加上标识以区别于参数为0" + message);        }
