How to Generate Random Integers in C# Using the Random Class?

Generating Pseudo-Random Integers in C#

The C# Random class is your go-to tool for creating pseudo-random integers. Let's explore how to effectively utilize it.

Using the Random Class:

1. Instantiate the Random object:

<code class="language-csharp">Random random = new Random();</code>

2. Generate a random integer within a specified range: Use the Next() method:

<code class="language-csharp">int randomNumber = random.Next(minimum, maximum);</code>

Here:

• minimum represents the inclusive lower bound.
• maximum represents the exclusive upper bound.

Illustrative Example:

To generate a random integer between 1 and 10 (inclusive):

<code class="language-csharp">int randomNumber = random.Next(1, 11); // Note: 11 is the exclusive upper bound</code>

Key Considerations:

• Reuse your Random object: For optimal results and to avoid generating duplicate sequences, it's best practice to reuse a single Random instance for multiple random number generations. Repeatedly creating new instances can lead to predictable sequences due to the reliance on the system clock for seeding.
