推荐答案

像这样修改你的逻辑

int[] items = { 60, 30, 40, 20, 80 };
int temp = 0;
int n = items.Length;
for (int i = 0; i < n; i++)
{
    for (int j = i ; j < n - i - 1; j++)
    {
        if (items[j] > items[j + 1])// here getting exception
        {
            temp = items[j];
            items[j] = items[j + 1];
            items[j+1] = temp;
        }

    }
    //Console.WriteLine("values:" + Convert.ToString(items[i]));

}

for (int i = 0; i < n; i++)
{
    Console.WriteLine("values:" + Convert.ToString(items[i]));
}

您获得例外的原因是您试图将商品[4]与商品进行比较[5]哪个不存在....

因此你需要将你的终止条件限制在nI-1



你也需要更改j的初始值...

The reason you are getting exception is you are trying to compare items[4] with items[5] which doesnot exists....
so you need to restrict you termination condition to n-I-1

and also you need to change the initial value of j ...
