在一个范围内使用C＃生成一个随机数
我如何去产生一个范围内的随机数字？
你可以试试
Random r = new Random(); int rInt = r.Next(0, 100); //for ints int range = 100; double rDouble = r.NextDouble()* range; //for doubles 看一下
随机类 ， Random.Next方法（Int32，Int32）和Random.NextDouble方法
就像是：
var rnd = new Random(DateTime.Now.Millisecond); int ticks = rnd.Next(0, 3000);
尝试下面的代码。
Random rnd = new Random(); int month = rnd.Next(1, 13); // creates a number between 1 and 12 int dice = rnd.Next(1, 7); // creates a number between 1 and 6 int card = rnd.Next(52); // creates a number between 0 and 51
使用：
Random r = new Random(); int x= r.Next(10);//Max range
除了生成整数和双精度的随机类以外，请考虑：
-
堆栈溢出问题生成（U）Int64和Decimal（伪）随机约束值
-
C＃RandomProvider类
// this is the code to generate numbers of Triangular series // [1,3,6,10,15,21,......n] int result=0; int count=0; Console.WriteLine("What is your range"); int range = int.Parse(Console.ReadLine()); Console.Clear(); for (int i = 0; i < range; i++) { count= count++; result = (result + count); Console.WriteLine(result); }
