抽奖源代码

Question

求  抽奖源代码！！！

Answer 1

同意楼上。
使用Random产生随机数来确定
eg:
Random rd = new Random();
rd.Next(0, 10000);//产生0到10000的随机数
eg:
Random rd = new Random((Int32)DateTime.Now.Ticks);  //using the specified seed value
Int32 i = rd.Next(0, 10000);

Answer 2

rd.Next(0, 10000);//产生0到10000的随机数不对,是 0-9999rd.Next(0, 10001);//产生0到10000的随机数80分....手很猛.LS几位都说出答案了.
我加点罗嗦.random是生成的伪随机数,是按当前系统时间 进行某些计算之后的结果.所以同1个毫秒之内产生的随机数必然是相同的.所以在应用的时候要稍微注意一下.

 List<Int32> list = new List<Int32>();
            while (true)
            {
               
                Random  r = new Random();
               int n = r.Next()%37;
               
               if (n != 0 && (!list.Contains(n)))
               {
                   list.Add(n);
               }
               if (list.Count == 7)
               {
                   break;
               }
            }            foreach (Int32 n in list)
            {
                Thread.Sleep(3000);
                Console.Write(n + "  ");

Answer 5

那更简单.........
用hashtable,
[key1][value1]
[key2][value2]
.....Random 结果是5的话 就选 key5的value5这个value5就是你要的结果字符串:220608
