[lucyskys]

如题，需求一个11选5的彩票算法，最好能随机选出数组的。。。谢谢！！！！

==我来写一个。哈哈

参考

/// <summary>  
        /// 从1到n中任意选取不重复的10个随机数  
        /// </summary>  
        /// <returns></returns>  
        private List<int> GenerateNumber()
        {
            //用于保存返回结果  
            List<int> result = new List<int>(10);
            Random random = new Random();
            int index = 0;
            int value = 0;
            for (int i = 1; i <= 10; i++)
            {
                //从[0,container.Count)中取一个随机值，保证这个值不会超过container的元素个数  
                index = random.Next(0, container.Count);//谢谢热心朋友指出这里的错误  
                //以随机生成的值作为索引取container中的值  
                value = container[index];
                //将随机取得值的放到结果集合中  
                result.Add(value);
                //从容器集合中删除这个值，这样会导致container.Count发生变化  
                container.RemoveAt(index);
            }
            //result.Sort();排序  
            return result;
        }

我还真拿出来的结果去买过，还真中过！
