将数组传递给函数(Passing arrays to functions)

您可以在C＃中将数组作为函数参数传递。 以下示例演示了这一点 -

using System;
namespace ArrayApplication {
   class MyArray {
      double getAverage(int[] arr, int size) {
         int i;
         double avg;
         int sum = 0;
         for (i = 0; i < size; ++i) {
            sum += arr[i];
         }
         avg = (double)sum/size;
         return avg;
      }
      static void Main(string[] args) {
         MyArray app = new MyArray();
         /* an int array with 5 elements */
         int [] balance = new int[]{1000, 2, 3, 17, 50};
         double avg;
         /* pass pointer to the array as an argument */
         avg = app.getAverage(balance, 5 ) ;
         /* output the returned value */
         Console.WriteLine( "Average value is: {0} ", avg );
         Console.ReadKey();
      }
   }
}

编译并执行上述代码时，会产生以下结果 -

Average value is: 214.4
