C#将数组参数传递给函数

在 C# 中将数组作为函数参数传递。以下是一个演示如何将数组传递到函数的示例：

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();
      }
   }
}

当编译和执行上述代码时，会产生以下结果：

Average value is: 214.4
