在开发中遇到了要将显示商品随机显示的需求，试用了很多的算法，发现该算法效率最高，写下了希望对大家有用。

??????? public void Reshuffle<T>(List<T> listtemp)
??????? {
??????????? //随机交换
??????????? Random ram = new Random();
??????????? int currentIndex;
??????????? T tempValue;
??????????? for (int i = 0; i < listtemp.Count; i++)
??????????? {
??????????????? currentIndex = ram.Next(0, listtemp.Count - i);
??????????????? tempValue = listtemp[currentIndex];
??????????????? listtemp[currentIndex] = listtemp[listtemp.Count - 1 - i];
??????????????? listtemp[listtemp.Count - 1 - i] = tempValue;
??????????? }
