C#实现随机洗牌的要领

#region 随机洗牌

int[] ints = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 };

List<int> list=ints.ToList();

int[] outs = new int[20];

Random rand = new Random();

for (int i = 0; i < 20; i++)

{

int x = rand.Next(list.Count);

outs[i] = list[x];

list.RemoveAt(x);

}

Response.Write(“<hr/>”);

foreach (int i in outs)

{

Response.Write(i.ToString() + ” “);
