C#选择排序

//int[] a = { 2, 3, 1, 1 };

           //int m = 0;

           //for (int i = 0; i < a.Length - 1; i++)

           //{

           //    m = i;

           //    for (int j = i + 1; j < a.Length; j++)

           //    {

           //        if (a[j] < a[m])//i=1，时第二个for循环只负责比，不负责换1321时，2和1比，1=temp，m=3  a[1]和a[3]换

           //        {

           //            m = j;

           //        }
