1. C#代码

1 1             Console.WriteLine("===============大乐透===红色球===============");
2 2             List<int> listRed = new List<int>();
3 3             Random rangdomRed = new Random();
4 4             for (int i = 0; listRed.Count < 5; i++)
5 5             {
6 6                 int redNum = rangdomRed.Next(1, 35);
7 7                 if (!listRed.Contains(redNum))
8 8                 {
9 9                     listRed.Add(redNum);
1010                     Console.Write("{0} ", redNum);
1111                 }

3333                 Console.Write("{0} ", listRed[i]);
3434             }
3535             listBlue.Sort();
