一、封装两种冒泡排序的方法

public class SortBy
    {
        /// <summary>
        /// 方式一：从后往前交换
        /// </summary>
        /// <param name="array"></param>
        public static void BubbleSort(int[] array)
        {

            int i, j, temp;
            int len = array.Length;

            for (i = 0; i < len - 1; i++)
            {
                for (j = len - 1; j > i; --j)
                {
                    if (array[j] < array[j - 1])
                    {
                        temp = array[j];
                        array[j] = array[j - 1];
                        array[j - 1] = temp;
                    }
                }
            }
        }

        /// <summary>
        /// 方式二：从前往后交换
        /// </summary>
        /// <param name="arr"></param>
        public static void BubbleSortAsc(int[] arr)
        {
            int temp = 0;
            for (int i = 0; i < arr.Length - 1; i++)
            {
                for (int j = 0; j < arr.Length - 1 - i; j++)
                {
                    if (arr[j+1] < arr[j])
                    {
                        temp = arr[j];
                        arr[j] = arr[j+1];
                        arr[j+1] = temp;
                    }
                }
            }
        }


    }

二、控制台调用

 class Program
    {
        static void Main(string[] args)
        {
            int[] arr = { 1, 3, 5, 10, 999, 632, -123, 985, 45, 32 };
            SortBy.BubbleSortAsc(arr);
            int[] arr2 = { 10, 30, 5, 110, 99, 32, -123, -985, 45, 32 };
            SortBy.BubbleSort(arr2);
            System.Console.WriteLine(string.Join(",", arr2)+Environment.NewLine+string.Join(",", arr));

        }
    }

三、输出效果
