How Can I Easily Generate Random Integers in C#?

C# random integer generation method detailed explanation

In C#programming, it is a common task to generate a random integer. So, how can we achieve it easily?

RANDOM class: the cornerstone generated random number

C# provides a powerful class, which is specifically used to generate random numbers. Although these numbers are called pseudo -random numbers, they are enough to meet the random needs of most application scenarios.

Next method: generate random integer with specified range Random

Class contains a method called , allowing you to generate a random integer within the specified range. This method accepts two integer parameters: lower bounds (including) and upper bounds (excluding).

For example:

Random Best Practice: Improve randomness Next

In order to maximize the randomness of random numbers, it is recommended to create a single

instance and reuse it in multiple operations. Repeating to create a new instance in a short time may lead to the same random number sequence, because the seeds are derived from the system clock.

<code class="language-csharp">Random rnd = new Random();
int month = rnd.Next(1, 13);  // 生成 1 到 12 之间的随机数
int dice = rnd.Next(1, 7);   // 生成 1 到 6 之间的随机数
int card = rnd.Next(52);     // 生成 0 到 51 之间的随机数</code>
