c#数组元素排序的问题

class Program

}
}
if (min != i)
{
t = myArray[i];
myArray[i] = myArray[min];
myArray[min] = t;

Console.WriteLine("排序后数组为： ");

}
}

代码就这样，为什么没排好序？只有两个数字位置变化了。

把输出部分拿到for循环外面即可。

 class Program
    {
        static void Main(string[] args)
        {
            int[] myArray = new int[10] { 10, 54, 34, 45, 4, 8, 38, 9, 7, 11 };
            Console.WriteLine("原始数组为： ");
            foreach (int number in myArray)
            {
                Console.Write(number + " ");
            }
            Console.WriteLine();
            int i, j, t, min;
            for (i = 0; i < 10; i++)
            {
                min = i;
                for (j = i + 1; j < 10; j++)
                {
                    if (myArray[j] < myArray[min])
                    {
                        min = j;
                    }
                }
                if (min != i)
                {
                    t = myArray[i];
                    myArray[i] = myArray[min];
                    myArray[min] = t;
                }
            }

            Console.WriteLine("排序后数组为： ");
            foreach (int number in myArray)
            {
                Console.Write(number + " ");
            }
            Console.ReadLine();
        }
    }

不需要使用什么冒泡算法，LINQ查询一行代码就可以搞定

             int[] myArray = new int[10] { 10, 54, 34, 45, 4, 8, 38, 9, 7, 11 };
            var query1 = myArray.OrderBy(val => val);//升序
            var query2 = myArray.OrderByDescending(val => val);//降序
            foreach (var item in query1)
           {
               Console.Write(item);
           }
            foreach (var item in query2)
            {
                Console.Write(item);
            }
