方法 函数

 方法（函数）

 

 

 

 

 

 

 

 

参数传递 （注意要写类型）

 

 static void Main(string[] args)
        {
            int a = 100;
            a = Test(a);
            Console.WriteLine(a);
            Console.ReadKey();
    
        }
        public static int Test(int a)
        {
            return a + 100;
        }

 

 

out，ref,paramse

 

返回数组

out

main函数

   out代表输出  方法不用返回值 返回值其实就是out **

 

 例子

 

main                           　　　　　　　　　　　　　　　　　　　　　　　　　　　　　方法

 

ref   （相当于python中的globle）

 

 

 

 

 

 

paramas   可变参数(相当于python  *args)  必须在形参列表最后一位

 

 

 

 

 方法重载

 

 

 

    

 

 

 递归
