Random.Next generates a random number whose value ranges from zero to less than int.MaxValue. To generate a random number whose value ranges from zero to some other positive number, use the Random.Next(int) method overload. To generate a random number within a different range, use the Random.Next(int, int) method overload.

The following example demonstrates using the Next method. The output generated by this example will vary.

using System;
class RandomTest {
    public static void Main() {
        Random rand1 = new Random();
        for (int i = 0; i<10;i++)
        Console.WriteLine("The random number is {0}",rand1.Next());
        
    }
}
   

The output is
