问一个关于ArrayList的问题

[winsvr2003]

如果我的arraylist里存放了100个整数
我想用random随机显示其中一个,并且每在button上点一次,这个随机显示的数要从arraylist里去掉,求大家帮忙,应该怎么写.谢谢了

Random rand=new Random();
int i=rand.Next(list.Count)
num=(int)list[i];
list.RemoveAt(i);

private void button1_Click(object sender, EventArgs e)
{
while (list.Count > 0)
{
Random rd = new Random();
int n = rd.Next(0, list.Count);
this.textBox1.Text = list[n].ToString();
//移除
list.RemoveAt(n);
}
}

sorry..手误

while->>if

如下：

private void button1_Click(object sender, EventArgs e)
{
if (list.Count > 0)
{
Random rd = new Random();
int n = rd.Next(0, list.Count);
this.textBox1.Text = list[n].ToString();
//移除
list.RemoveAt(n);
}
}
