c# 计算一个整型数组的平均

一个整型数组的平均：

 class Program
    {
        static void Main(string[] args)
        {
            int[] array = {1,2,3,4,5,6,7,8,9,10};
           double avg= GetAvg(array);
            Console.WriteLine("数组的平均值是：{0}",avg);
            Console.ReadKey();
        }
        /// <summary>
        /// 求数组的平均值
        /// </summary>
        /// <param name="array"></param>
        /// <returns></returns>
        private static double GetAvg(int[] array)
        {
            double sum = 0;
            for (int i = 0; i < array.Length; i++)
            {
                sum += array[i];
            }
            double avg = sum/array.Length;
            return avg;
        }
    }
