函數_方法_的四種調用方式

class Program{/// <summary>/// 無參數，無返回值/// </summary>/// <param name="args"></param>static void  n1(){Console.WriteLine("這是第一種方法");}/// <summary>/// 有參數，無返回值/// </summary>/// <param name="args"></param>static  void n2(string  a)               //這里必須是靜態
    {Console.WriteLine(a);}/// <summary>/// 無參數，有返回值/// </summary>/// <returns></returns>static int n3(){return 100;}/// <summary>/// 有參數有，返回值/// </summary>/// <param name="args"></param>static int n4(string name){Console.WriteLine(name);return 100;}static void Main(string[] args){n1();Console.WriteLine("請輸入一個字符串");string s = Console.ReadLine();n2(s);int b=n3();Console.WriteLine("返回值為" + b);int  i = n4("有參數，有返回值");Console.WriteLine("返回值為" + i);Console.ReadLine();}   }
