c#冒泡排序从小到大 求详细代码。

int temp = 0;
int[] arr = { 23, 44, 66, 76, 98, 11, 3, 9, 7 };
Console.WriteLine("排序前的数组：");
foreach (int item in arr)
{
Console.Write(item + "");
}
Console.WriteLine();
for (int i = 0; i < arr.Length - 1; i++)
{
for (int j = 0; j < arr.Length - 1 - i; j++)
{
if (arr[j] > arr[j + 1])
{
temp = arr[j + 1];
arr[j + 1] = arr[j];
arr[j] = temp;
}
}
}
Console.WriteLine("排序后的数组：");
foreach (int item in arr)
{
Console.Write(item + "");
}
Console.WriteLine();
Console.ReadKey();
