When button clicked again do other action

Question

So I am making a tool for PS3 however I need help on making a button do another action when clicked again, this is what I have but I am getting errors, thanks.

private void metroButton2_Click(object sender, EventArgs e)
    {
        byte[] On = new byte[] { 0x00 };
        PS3.SetMemory(0x007EDCA4, On);
    }
    else
    {
        byte[] On = new byte[] { 0x65 };
        PS3.SetMemory(0x007EDCA4, Off);
    }

Looks like you missing `if` statement and curly brackets of the method — J-Alex, May 27 '17 at 20:56
nvm, I'm new to coding only know small things I don't know what I'm doing right now :P — Ron Burgundy, May 27 '17 at 21:06
please check my suggested edit and apply if it's suitable to your real code, or reject and fix it yourself — J-Alex, May 27 '17 at 21:12

I see what you're trying to do but you can't use an else statement that way. The else keyword can only be used following an "if" statement. What you'll need is some kind of flag (a bool variable) which you switch between true and false to swap the button_click event's execution.

bool metroBtnFlag = true;
private void metroButton2_Click(object sender, EventArgs e)
{
   if (metroBtnFlag)
   {
       metroBtnFlag = false;
       //First, third, fifth, etc... click events
   }
   else
   {
      metroBtnFlag = true;
      //Second, fourth, sixth, etc... click events
   }
}

Alternatively, if you only want the button to do something the first time, and then do something different every other time, just remove one of the flag assignments. That way, when its set to false, it will never execute the first block of code again.
