C# -- 随机数(Random)的使用

使用随机数产生一组大乐透号码

1. C#代码

 1             Console.WriteLine("===============大乐透===红色球===============");
             List<int> listRed = new List<int>();
             Random rangdomRed = new Random();
             for (int i = ; listRed.Count < ; i++)
             {
                 int redNum = rangdomRed.Next(, );
                 if (!listRed.Contains(redNum))
                 {
                     listRed.Add(redNum);
                     Console.Write("{0} ", redNum);
                 }

             }
             Console.WriteLine();
             Console.WriteLine("===============大乐透===蓝色球================");
             List<int> listBlue = new List<int>();
             Random rangdomBlue = new Random();
             for (int i = ; listBlue.Count < ; i++)
             {
                 int blueNum = rangdomBlue.Next(, );
                 if (!listBlue.Contains(blueNum))
                 {
                     listBlue.Add(blueNum);
                     Console.Write("{0} ", blueNum);
                 }
             }

             Console.WriteLine();
             Console.WriteLine("===============排序=============");
             listRed.Sort();
             for (int i = ; i < listRed.Count; i++)
             {
                 Console.Write("{0} ", listRed[i]);
             }
             listBlue.Sort();
             for (int i = ; i < listBlue.Count; i++)
             {
                 Console.Write("{0} ", listBlue[i]);
             }
             Console.WriteLine();

             Console.ReadKey();
