C#产生并输出8个随机2位数；然后，排序输出。

C#程序设计教程。。。

static void Main(string[] args)
{
int numlenth=8;
int[] num = new int[numlenth];
int temp;
for (int i = 0; i < num.Length; i++)
{
Random rand = new Random();
num[i] = rand.Next(10, 99);
Thread.Sleep(200); //这里需要using System.Threading；因为程序执行太快，让它睡会，才会得到不同的随机数，不然就会得到8个相等的数，或者在new Random()这里做个时间种子....

}
Console.WriteLine("排序前：");
foreach (int i in num)
{
Console.Write(i);
Console.Write(" ");
}
Console.WriteLine();
for (int i = 0; i < num.Length - 1; i++)
{
for (int j = 0; j < num.Length - 1 - i; j++)
{
if (num[j] > num[j + 1])
{
temp = num[j];
num[j] = num[j + 1];
num[j + 1] = temp;

}
}
}

Console.WriteLine("排序后：");
foreach (int i in num)
{
Console.Write(i);
Console.Write(" ");
}

Console.ReadLine();
}

form中放两个txt  txt1为奇数  txt2为偶数 private void btn_click(object sender, eventargs e)         {             arraylist arr = new arraylist();             random rd = new random();             for (int i = 0; i             {                 arr.add(rd.next(1, 101));             }             arr.sort();             foreach (int i in arr)             {                 if ((i % 2) == 0)                 {                     txt2.text += i + ",";                 }                 else                 {                     txt1.text += i + ",";                 }             }             txt1.text = txt1.text.trim(',');             txt2.text = txt2.text.trim(',');         } 执行前： 执行后：

Random r = new Random(); int n=8; int[] a; a = new int[n]; for (int i = 0; i < n; i++) { int x; //= r.Next(100); do { x=r.Next (100); } while (!(x >= 10 && x <= 99)); a[i] = x; }
