Hi!
In this chapter I’m going to describe how to generate random numbers in C#. There are different ways to do this:
1.- Specifying INCLUSIVE Minimum and EXCLUSIVE Maximum values.
2- Specifying EXCLUSIVE Maximum value, which generates a number between “0” INCLUDED and Maximum value EXCLUDED
3.- No value in the overload constructor. This generates random integer numbers
Check the example code below:
private void button2_Click(object sender, EventArgs e)
{
Random r = new Random();
Console.WriteLine("Generate 10 random numbers with Min and Max values specified");
for (int i = 0; i < 10; i++)
{
Console.WriteLine(r.Next(1, 11).ToString());
}
Console.WriteLine("\nGenerate 10 random numbers with only Max value specified");
for (int i = 0; i < 10; i++)
{
Console.WriteLine(r.Next(11).ToString());
}
Console.WriteLine("\nGenerate 10 random integer numbers");
for (int i = 0; i < 10; i++)
{
Console.WriteLine(r.Next().ToString());
}
}
Output in console box:
Generate 10 random numbers with Min and Max values specified
