C#声明方法，不参数数目时

 class testclass
 {
      public static void test(params int[] array)
      {
         string s;foreach (int i in array)
         {
           console.wrriteline(i);
         }
       
      }
   }
     
  


      public static void main(string[] args)
      {
        testclass.test("a","b","c","d");
      }
