increment by 2 instead of 1 after button is clicked

Question

This is my code

int Moneycount;
        private void mButton_Click(object sender, EventArgs e)
        {
            Moneycount++;
            MoneyCount.Text = Moneycount.ToString();
        }
        private void level1_Click(object sender, EventArgs e)
        {
        }

"mButton" is incremented by 1 every time I press it,

so I want it to be incremented by 2 instead of 1 after I press "level1"

Answer 1

So if I understand you correctly, you want mButton to increment MoneyCount by one every time you press it. But after pressing level1, mButton should increment by 2 instead.

Try this:

int Moneycount;
int amountToIncrement = 1;
private void mButton_Click(object sender, EventArgs e)
{
    Moneycount += amountToIncrement;
    MoneyCount.Text = Moneycount.ToString();
}
private void level1_Click(object sender, EventArgs e)
{
    amountToIncrement = 2;
}

Answer 2

Try

Moneycount += 2;

this increments by two

Answer 3

Instead of level1 being an actual Button , it might be useful to make it a Checkbox instead, and then make it look like a button by setting the Appearance property to Button in the designer. Here is a simple example where clicking on mButton looks at the Checked state of level1 to determine the correct increment value. At the same time, toggling the checked state of level1 sets the Increment value of the NumericUpDown control so that the Up/Down arrows also use the correct value of 1 or 2.

Example of coding the MainForm that has the behavior you describe:

public partial class MainForm : Form , INotifyPropertyChanged
{
    public MainForm()
    {
        InitializeComponent();
        level1.Appearance = Appearance.Button;
        numericUpDown.DataBindings.Add(
            nameof(NumericUpDown.Value), 
            this, 
            nameof(Moneycount),
            false,
            DataSourceUpdateMode.OnPropertyChanged);
    }
    private void mButton_Click(object sender, EventArgs e)
    {
        Moneycount += level1.Checked ? 2 : 1;
    }
    private void level1_CheckedChanged(object sender, EventArgs e)
    {
        // Clicking up/down arrows increments 1 or 2
        numericUpDown.Increment = level1.Checked ? 2 : 1;
    }
    public int Moneycount
    {
        get => _moneyCount;
        set
        {
            if(!Equals(_moneyCount, value))
            {
                _moneyCount = value;
                PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(nameof(Moneycount)));
            }
        }
    }
    int _moneyCount = 0;
    public event PropertyChangedEventHandler PropertyChanged;
}
