c# - How to pass button object to function

Question

I have several buttons to click, and all the same function (that I want to create), they just differ by controller's name. For example:

private void markX()
        {
            buttonName.Text = "X";
            buttonName.ForeColor = System.Drawing.Color.Red;
        }

How can I pass the button object that that is modified in the function into the function's parameters?

Answer 1

Make it a Click event handler, attach it to each button, and use the sender parameter as the button to change.

void button_Click(Object sender,  EventArgs e)
{
    var button = sender as Button;
    if(button != null)
    {
        button.Text = "X";
        button.ForeColor = System.Drawing.Color.Red;
    }

}
