c# 计算一个整型数组的平均

一个整型数组的平均：
 1  class Program
 2     {
 3         static void Main(string[] args)
 4         {
 5             int[] array = {1,2,3,4,5,6,7,8,9,10};
 6            double avg= GetAvg(array);
 7             Console.WriteLine("数组的平均值是：{0}",avg);
 8             Console.ReadKey();
 9         }
10         /// <summary>
11         /// 求数组的平均值
12         /// </summary>
13         /// <param name="array"></param>
14         /// <returns></returns>
15         private static double GetAvg(int[] array)
16         {
17             double sum = 0;
18             for (int i = 0; i < array.Length; i++)
19             {
20                 sum += array[i];
21             }
22             double avg = sum/array.Length;
23             return avg;
24         }
