Random button color ?

GaLaZ

Hi,

I've just begun with C# and I've encountered a problem...

I've got 25 buttons on my windows form, they all have black background... My objective is to randomly assign them one of 2 colors (black, white), when my application starts. How can I solve my problem? Could you help me?

Thanks,

Gregory

If you want to implend more colors in the future you could precreate some in an color array and randomly pick them one out ;)

private void button1_Click(object sender, EventArgs e)

{

Random rand = new Random();

Color[] c = { Color.SeaShell, Color.SpringGreen, Color.Teal, Color.Tomato, Color.WhiteSmoke };

this.button1.BackColor = c[rand.Next(0, c.Length)];

}

Or you could randomly generate colors

private void button1_Click(object sender, EventArgs e)

{

Random randomizer = new Random();

int r = randomizer.Next(0,255), g = randomizer.Next(0,255), b = randomizer.Next(0,255);

this.BackColor = Color.FromArgb(r, g, b);

}

You have only 2 colors. I doesn't really sound random ;)

Anyway, you can generate a random number between 1 and 2. If number is 1, assign white color and if the number is 2, assign black color. Search this site for ranom number to see how to generate a random number.
