list 随机排列

做标签云是想让标签随机排放，写了一个算法，留作以后用，很方便，效率很高。

protected void Page_Load(object sender, EventArgs e)
{
//随进生成70个三位数的int32数组
List<int> list = new List<int>();
//初始化数据
for (int i = 1; i < 50; i++)
list.Add(i);
//重新排序
StringBuilder sb = new StringBuilder();
list = RandomSortList(list);
sb.Append("<div>");
foreach (int i in list)
{
sb.Append("<a href='#'>");
sb.Append(i);
sb.Append("</a>&nbsp;");
}
sb.Append("</div>");
Label1.Text = sb.ToString();
}

public List<T> RandomSortList<T>(List<T> ListT)
{
Random random = new Random();
List<T> newList = new List<T>();
foreach (T item in ListT)
{
newList.Insert(random.Next(newList.Count+1), item);
}
return newList;
}
