我如何生成在C＃中随机整型数字？

How do I generate a random int number in C#?

推荐答案

的 随机类用于创建随机数。 （伪随机那是当然的）。

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

例如：

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

如果您要创建多个随机数，你应该保持随机实例，并重新使用它。如果创建新实例太接近的时间，他们将作为随机发生器从系统时钟接种产生相同的随机数序列

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.
