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 = {,,,,,,,,,};
            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 = ;
             for (int i = ; i < array.Length; i++)
             {
                 sum += array[i];
             }
             double avg = sum/array.Length;
             return avg;
         }
     }
