Question

I’ve just started programming meaning I’m new… I’ve made a tic tac toe game using else if statements.

The code below is code that will reset certain values within my game, I’m sure there’s but I can’t find an answer – How do I shorten this block of code?

        btn1.Enabled = true;
        btn2.Enabled = true;
        btn3.Enabled = true;
        btn4.Enabled = true;
        btn5.Enabled = true;
        btn6.Enabled = true;
        btn7.Enabled = true;
        btn8.Enabled = true;
        btn9.Enabled = true;

        btn1.Text = "";
        btn2.Text = "";
        btn3.Text = "";
        btn4.Text = "";
        btn5.Text = "";
        btn6.Text = "";
        btn7.Text = "";
        btn8.Text = "";
        btn9.Text = "";

        btn1.BackColor = default(Color);
        btn2.BackColor = default(Color);
        btn3.BackColor = default(Color);
        btn4.BackColor = default(Color);
        btn5.BackColor = default(Color);
        btn6.BackColor = default(Color);
        btn7.BackColor = default(Color);
        btn8.BackColor = default(Color);
        btn9.BackColor = default(Color);

You should use an array, or better yet, a generic list which will hold all your buttons.

For example:

 List<Button> buttonList = new List<Button>();

 // Add buttons to list...
 buttonList.Add(btn1);
 buttonList.Add(btn2);
 ...

Then, you can iterate on the list like this:

foreach (Button btn in buttonList)
{
     btn.Text = "";
     btn.BackColor = default(Color);
} 

The code above will run on all the buttons in the list and for each of them clear the text and set the BackColor.
