c#冒泡排序示例分享

冒泡排序口诀：

升序（从小到大）：两for一if；大于连；相 交换；再来个for遍历；外层n-1;内层n-1-i；

说再多不如上代码，更明显：

class program
    {
        static void main(string[] args)
        {
            int[] array = {1, 3, 5, 7, 90, 2, 4, 6, 8, 10};
            array= getsort(array);
            for (int i = 0; i < array.length; i++)
            {
                console.write(array[i] + " ");
            }
            console.readkey();
        }
        /// <summary>
        /// 冒泡排序
        /// </summary>
        /// <param name="array"></param>
        /// <returns></returns>
        private static int[] getsort(int[] array)
        {
            //外层循环n-1
            for (int i = 0; i < array.length-1; i++)
            {
                //内层循环n-1-i
                for (int j = 0; j < array.length-1-i; j++)
                {
                    if (array[j] > array[j+ 1])
                    {
                        int temp = array[j];
                        array[j] = array[j + 1];
                        array[j + 1] = temp;
                    }  
                }
            }
            return array.toarray();
        }
    }
