How can I switch between two methods in one button with every click?

I am new on C# so sorry if it look easy for some of you :)

I have this button click:

private void buttonSwitchCamera_Click(object sender, RoutedEventArgs e)
{
        _blManager.SendTrackerCmd(TrackerCmdType.PrimaryAVT_ActiveSensor, (float)IR_Id.IR_1); // Switch to IR1
        _blManager.SendTrackerCmd(TrackerCmdType.PrimaryAVT_ActiveSensor, (float)IR_Id.IR_2); // Switch to IR2
}

How can I switch between the two methods when clicking the button?

one click will be for method #1

second click will be for method #2

third click will be for method #1

etc..

First click is old:

    private void OnButtonClickOdd(object sender, RoutedEventArgs e)
    {
        // Unsubscribe OnButtonClickOdd
        button.Click -= OnButtonClickOdd;

        // Subcribe to OnButtonClickEven
        button.Click += OnButtonClickEven;

        // Do your job here
    }

    private void OnButtonClickEven(object sender, RoutedEventArgs e)
    {
        // Unsubscribe OnButtonClickEven
        button.Click -= OnButtonClickEven;

        // Subcribe to OnButtonClickOdd
        button.Click += OnButtonClickOdd;

        // Do your job here
    }

Other way: just use bool flag to know it odd or even click:

private bool odd = true;

private void buttonSwitchCamera_Click(object sender, RoutedEventArgs e)
{
    if(old)
    {
         // Odd click job
    }
    else
    {
         // Even click job
    }
    old = !old;
}

You can do something like that:

bool executeMethodOne;

private void buttonSwitchCamera_Click(object sender, RoutedEventArgs e)
{
   executeMethodOne = !executeMethodOne;

   var IrId = executeMethodOne ? IR_Id.IR_1 : IR_Id.IR_2;

    _blManager.SendTrackerCmd(TrackerCmdType.PrimaryAVT_ActiveSensor, (float)IrId);
}

Have a bool called executeMethodOne which you will invert everytime you click on the button. Depending on if it is true or false you can execute the first or the second method
