How Can I Generate Random Integers in C# Effectively?

C# random integer generation: comprehensive guide

In programming, it is a common task to randomly generate an integer. C# offers a powerful

class that allows developers to easily generate pseudo -random numbers.

Random Use the Random class

To generate a random integer with C#, you can instantly instance a object and use its

method.

Method accepts two parameters: the starting value and end value (excluding the end value). For example, the following code generates a random integer between 1 and 12: Random Next() Next() Similarly, you can generate random integers in other areas, such as generating dice points between 1 and 6:

Random rnd = new Random();
int month  = rnd.Next(1, 13);

<用> Reuse the Random instance

int dice   = rnd.Next(1, 7);

It should be noted that creating multiple instances in a short time may cause the same random number sequence. This is because the use system clock as seeds. To avoid this, it is recommended to create a

instance and reuse it for multiple random numbers.

Random For example, you can create a Random instance in the class constructor and use it in the entire class: Random

By reusing the instance, you can ensure that the generated random number sequence is unique to each instance of your class. Random
