如何在C#中生成随机整数?

How do I generate a random integer in C#?

推荐答案

Random类用于创建随机数. (当然是伪随机的.)

The Random class is used to create random numbers. (Pseudo-random that is of course.).

示例:

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

如果要创建多个随机数，则应保留Random实例并重新使用它.如果您创建的新实例在时间上过于接近，则它们将产生与从系统时钟中植入随机生成器相同的一系列随机数.

If you are going to create more than one random number, you should keep the Random instance and reuse it. If you create new instances too close in time, they will produce the same series of random numbers as the random generator is seeded from the system clock.
