C# program to generate random numbers

The source code to generate random numbers in C# is given below. The given program is compiled and executed successfully on Microsoft Visual Studio.

//Program to Generate Random Numbers in C#.

using System;

class RandomEx
{
    static void Main()
    {
        int num = 0;
        Random R = new Random();

        Console.WriteLine("Random Numbers: ");
        for (int i = 1; i < 10; i++)
        {
            num = R.Next();
            Console.WriteLine(num);    
        }
    }
}

Output

Random Numbers:
1396315331
747908140
1390110439

Explanation

In the above program, we created the RandomEx class that contains Main() method, In the Main() method we created the object R of Random class.

Console.WriteLine("Random Numbers: ");
for (int i = 1; i < 10; i++)
{
    num = R.Next();
    Console.WriteLine(num);    
}

Here we used the Next() method to generate random numbers and then print them on the console screen.
