c# random number generator
Random Class
Represents a pseudo-random number generator, which is an algorithm that produces a sequence of numbers that meet certain statistical requirements for randomness.
public class Random
The Random class is used to create random numbers.
c# random number
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
- If you are going to create more than one random number, you should keep the Random instance and reuse it.
c# random
Create a Random object
Random rand = new Random();
and use it
int randomNumber = rand.Next(min, max);
- You don’t have to initialize
new Random()every time you need a random number, initiate one Random then use it as many times as you need inside a loop.
pick a number between 1 and 30
using System; class HelloWorld { static void Main() { Random rand = new Random(); int randomNumber = rand.Next(1, 30); Console.WriteLine(randomNumber); } }
random number 1 7
using System; class HelloWorld { static void Main() { Random rand = new Random(); int randomNumber = rand.Next(1, 7); Console.WriteLine(randomNumber); } }
random number between 1 and 23
using System; class HelloWorld { static void Main() { Random rand = new Random(); int randomNumber = rand.Next(1, 23); Console.WriteLine(randomNumber); } }
