I have a total of 12 buttons on my designer. I added 3 of them into a List because I want to apply a specific style to those. For the remaining buttons, I want to perform different actions .

Here’s the method I defined:

public void ButtonEvents()
{
    List

mybuttonlist = new List(); mybuttonlist.Add(button1); mybuttonlist.Add(button2); mybuttonlist.Add(button3); foreach (Button button in mybuttonlist) { button.BackColor = Color.FromArgb(242, 242, 242); } foreach (Control control in this.Controls) { if (control is Button button && !mybuttonlist.Contains(button)) { button.BackColor = Color.Black; } } }
