How do I Generate a Random Integer in C#? – ..

To generate a random integer in C#, you can use the Random class from the System namespace.

Here’s an example:

Example: Generate a Random Integer

sharp Copy code

using System;

class Program

{

static void Main()

{

// Create a Random object

Random random = new Random();

// Generate a random integer

int randomNumber = random.Next(); // Generates a non-negative random integer

Console.WriteLine(“Random Number: ” + randomNumber);

// Generate a random integer within a range (e.g., 1 to 100)

int randomInRange = random.Next(1, 101); // Upper bound is exclusive

Console.WriteLine(“Random Number (1-100): ” + randomInRange);

}

}

Key Points:

Random.Next():

Without parameters: Generates a random integer from 0 to Int32.MaxValue (inclusive).

With parameters: Next(int minValue, int maxValue) generates a random integer between minValue (inclusive) and maxValue (exclusive).

Reusability:

Avoid creating multiple Random objects in a short time (e.g., in a loop) to ensure randomness, as they may use the same seed.
