How do I generate a random int number?

Question

How do I generate a random integer in C#?

Answer 1

Try these simple steps to create random numbers:

Create function:

private int randomnumber(int min, int max)
{
    Random rnum = new Random();
    return rnum.Next(min, max);
}

Use the above function in a location where you want to use random numbers. Suppose you want to use it in a text box.

textBox1.Text = randomnumber(0, 999).ToString();

0 is min and 999 is max. You can change the values to whatever you want.
