在 C# 中將陣列作為函式引數傳遞。以下是一個演示如何將陣列傳遞到函式的範例:

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();
      }
   }
}

當編譯和執行上述程式碼時,會產生以下結果:

Average value is: 214.4
