Question

如何将数组的一个属性当做参数传入

Answer 1

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();
/* 一个带有 5 个元素的 int 数组 */弯老
int [] balance = new int[]{1000, 2, 3, 17, 50};
double avg;

/* 传递数组的指针作为参数 */困搜
avg = app.getAverage(balance, 5 ) ;

/* 输出返回汪闹历值 */
Console.WriteLine( "平均值是： {0} ", avg );
Console.ReadKey();
}
}
}
